dmesg after starting kernel with pci=noacpi

This is a brand new notebook on the market with Ryzen 5/Radeon. With disabled ACPI kernel boots without any problem but my notebook produces more heat than on Win10. Otherwise this happens when it is stayed on the bios screen in a while.
Comment 1 bakarichard91 2018-06-16 04:51:39 UTC
CPU: AMD Ryzen 5 2500U
GPU1: AMD Radeon Vega 8
GPU2: AMD Radeon 535

(I wrote to Acer to fix their bios problems but they said Linux is not supported. I don't think they are right but what can I do?)

Comment 13 bakarichard91 2018-07-13 18:58:45 UTC
Hi, I was trying another kernel parameters and noapic seems to work. It is not needed to disable the whole ACPI "service", however I don't know how important apic is. On kernel 4.18 even temperature sensors appear.
Power management is almost perfect if cpu governor is set to powersave.

At least amdgpu crashes now so kernel doesn't start without nomodeset. Could this be an acpi problem or I should ask kernel firmware developers?
Comment 14 gg71 2018-07-13 21:33:30 UTC
Hi, 
amdgpu doesn't crash on my a315-41g-r40x (BIOS V1.08) with  
  linux-next-next-20180713 compiled with VGA_SWITCHEROO=N 
and with 
  kernel parameters: ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2

Comment 17 bakarichard91 2018-07-23 05:32:52 UTC
Zhang Rui,

why have you changed the topic? It was correct, the kernel loads only with noapic or noacpi. The problem is DSDT/SSDT tables can not load because of ALREADY_EXIST problem. They should be fixed by someone correctly.

with kernel parameters "ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 iommu=pt" on kernel 4.18.5 my a315 41g laptop works flawlessly without crashes or kernel panics, however one issue is that afte resuming from sleep lscpu reports that the cpu runs constantly at turbo frequency
Comment 22 siyia 2018-09-16 11:42:03 UTC
suspend crashes sometimes with a screen freeze only way is to reboot the laptop. kernel 4.18.8
Comment 23 Darksurf 2018-10-01 17:24:17 UTC
I'm currently have the exact same issue with my AN515-42-R5GT Acer Nitro 5 Ryzen 2500U + RX560X.

Adding:
ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 iommu=pt 

Seemed to help me out on 4.19rc2, but 4.18.10 requires noapic on Sabayon Linux.

Tell me whatever you need an I'll pull it all.
Comment 24 bakarichard91 2018-10-03 20:34:45 UTC
Hi bros,

I can upload the SSDT/DSDT tables if somebody will fix them. Something should be invented because that is not too good if linux desktops can not be used on new notebooks.
Comment 25 siyia 2018-10-06 06:56:57 UTC
guys linpus Linux is fedora based that's why it doesn't need noapic to boot, linpus Linux is pre-installed and supported on Acer laptops, so we got to find what quirks is fedora using to load the bios tables correctly.
Comment 26 siyia 2018-10-06 07:04:25 UTC
or maybe extract the ssdt dsdt tables after installing fedora on the laptop
Comment 27 Vladislav Kamenev 2018-10-10 20:21:41 UTC
Acer Aspire A315-41G-RX8R (Ryzen 5 2500u, no dGPU version).

From 4.16 to 4.18 kernels i'm required to use noapic to boot, yet i can't hibernate or suspend. Kernel panics after screen goes black.
On 4.19rc7 i can use iommu=pt ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 parameters and hibernation doesn't go kernel panic anymore.
Comment 28 siyia 2018-10-10 20:26:09 UTC
on kernel 4.19rc7 cannot power off the laptop. acer aspire a315 41g with ryzen 3 2200u and radeon 535
Comment 29 Samantha McVey 2018-10-10 23:47:47 UTC
I may be experiencing the same bug. I have a Lenovo A485 2700U. Though the system either doesn't progress past grub's "loading initramfs" or shows a black screen after that point.

Starting with pci=noacpi causes something to show up but it still does not boot.

But, with a different kernel config the latest git works fine, but when I compiled with my normal config it would not boot. Also, ubuntu's PPA which has rc7 in it has the same issue as my normal config. I am uploading my working and non-working config.

(here is the issue I originally reported my issue on https://bugs.freedesktop.org/show_bug.cgi?id=108307)

Hi Samantha,

thanks for your post that is a very intresting point. I thought there was something difference between the kernels of different distros but I didn't realize that could be caused by the pre-compile config but it's logical.

However I'm afraid this could be just a workaround and not a correct solution. Could you please check if you have correct ACPI functionality? I need a dmesg output with the correct kernel and please check if the CPU's temperature goes under 50C/122F on idle.

Thanks again.

dmesg from working kernel

Okay, here is my dmesg output.
Comment 34 bakarichard91 2018-10-11 00:41:42 UTC
Don't somebody want to make a comparsion (diff) from parameter to parameter? I fixed my tables manually so I don't really have motivation for that.

This section can be the most important for us: "Power management and ACPI options"

Otherwise the main problem is that the kernel's ASL (interpreter/compiler/decompiler idk.) can't interpret the ACPI tables because of failures like this: "ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog". If I want to decompile it with iasl the message is the same so I need to skip some SSDT files to avoid this. After "decompile(ing)" had been successful I need to fix a lot of bug for the recompile(ing).

suspend/resume on non graphical tty2 never crashes, suspend /resume on graphical x session sometimes causes screen freeze and you have to reboot the laptop.

i disabled polkit auth agent from openbox autostart and now the laptop sleeps like a baby, it was unrelated to acpi.

actually ignore my previous post i managed to crash suspend /sleep at a non graphical session, this could still be related to acpi or drivers.

siyia: I see you only have rcu_nocbs=0-3 but there are 8 logical cores. Try seeing if using `rcu_nocbs=0-7 idle=nomwait` helps. Both those together fixed my system lockups. With just rcu_nocbs for all my cores I still got lockups (and you don't have it enabled for all cores). Ryzen Errata: https://support.amd.com/TechDocs/55449_Fam_17h_M_00h-0Fh_Rev_Guide.pdf

i only get lockups only after/before suspend sometimes, otherwise the laptop is rock solid. however thanks Samantha for the idle=nowait boot parameter it solved the cpu power save feature.
Comment 47 Samantha McVey 2018-10-15 13:35:05 UTC
siyia: Only thing else I'd think to try would be this: https://gist.github.com/60b73ff4e6ce901d09f9a8025826cb4a It must be run as root and you must have `msr-tools` installed.

I wrote it just now based on https://lists.freebsd.org/pipermail/freebsd-current/2018-June/069799.html It sets some MSR registers that AMD specified as mitigations for some of the errata.

Let me know if that changes anything. (also I'm glad the kernel options somehow fixed the turbo issue for you).
Comment 48 siyia 2018-10-15 15:32:34 UTC
your script didn't help, about the powersave it was enabled by adding amdgpu in the modules in mkinitcpio.conf and then updating iniframs with sudo mkinitcpio - p linux that fixed it, however after waking from suspend cpu runs at turbo frequency again.
Comment 49 Samantha McVey 2018-10-16 21:44:40 UTC
siyia: I seem to be getting freezing during suspend too (though you seem to be getting it more than I). There are some with Ryzen that their crashes were fixed if they disabled C6 powerstate. Since I use a laptop that was mostly a non-option for me, but I wrote as script so systemd will disable C6 sleep before suspend and then enable it again after suspend (so CPU doesn't happen to be in C6 state aronud suspend time).

May or may not work. Since it has only happened every once in a while for me, I may not know for several days if the fix worked or not. You can test it out by putting https://gist.github.com/samcv/0b6a915aadcddc0e19640c20d9dd3164 as
/usr/lib/systemd/system-sleep/disable-enable-c6-state.sh and doing `chmod +x /usr/lib/systemd/system-sleep/disable-enable-c6-state.sh`. You will need download https://github.com/r4m0n/ZenStates-Linux/blob/master/zenstates.py and then set the ZENSTATES variable in my `disable-enable-c6-state.sh` script to wherever you put the script. If the script is working you should get an output from `journalctl -b 0 | grep -Ei '(enabled|disabled)\s*c6'` after you have done a suspend/resume cycle. If that doesn't fix it, your issue (and possibly mine depending on how my results go) should probably have their own bug filed.
Comment 50 siyia 2018-10-16 22:56:14 UTC
still freezes with c6 disabled, only anomaly I can detect is that after resuming from sleep cpupowersave is disabled and cpu runs at turbo frequency. only way to reverse this is to reboot and have the amdgpu module initiated early in km.

Comment 54 Samantha McVey 2018-10-27 19:36:19 UTC
Hmm, maybe a different configuration of the kernel or a different version? Not sure what kernel Fedora uses.

BTW the latest 1.05 BIOS update on my Lenovo A485 fixes the underlying BIOS issue, so my system doesn't suffer from this issue anymore (doesn't mean a kernel fix wouldn't be a good idea, since not all OEM's are good about fixing issues for "unsupported platforms").

i just cannot understand how fedora kernel config can fix buggy acer bios?i mean the tables are completely broken,yet under fedora the load without any error,can this be replicated upstream,fedora 29 uses kernel 4.18.16.

Is there a way to build\use fedora kernel under Arch or Ubuntu? Could be a workaround for some time.
Comment 57 siyia 2018-10-29 10:46:38 UTC
we could use the same config...,if we use the same config and the problem persists then it is probably a fedora kernel patch that fixes the issues with Acer Aspire A315-41G series.

Fedora 29 really do not show any errors?
On 28 there was two lines in dmesg "ioapic[4] not in ivrs table" which present on screenshot attachment for this bugreport.
And third line was like "switching irq routing to physical flat" - sorry, i'm not remember exactly... I did not find anything useful about this "physical flat" irq mapping mode. But seems this is similar to noapic.

Comment 65 siyia 2018-10-30 17:34:11 UTC
what they did works only after installing and booting fedora in bare metal,the live install cd still requires noapic
Comment 66 siyia 2018-10-30 20:28:26 UTC
installing fedora with ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 instead of noapic,produces the same soft lockup that ubuntu/arch gets.installing it with noapic allows you to boot without any custom parameters and acpi seems to work good.
Comment 67 siyia 2018-10-31 09:30:37 UTC
ok i figured this out.it's more like fedora has acpi working on these laptops with noapic.Other distros with noapic cannot sleep but fedora can.

I'm using A315-41-R8XR which doesn't have an dGPU and yet can't sleep with noapic. Could you please specify which wi-fi adapter (lspci -k) you are using?

I cannot reboot,shutdown,suspend in fedora with kernel 4.19.2, kernel 4.18.6 works fine,no errors in dmesg, how is kernel 4.19.x working for you in various distros?
Comment 74 Ziniral 2018-12-01 22:25:25 UTC
I don't know if it is the same problem, but the Lenovo notebooks Lenovo E585 and Lenovo E485 with Ryzen 5 2500U or Ryzen 7 2700U also do not boot on Linux. This is very frustrating, because you have to add command lines to GRUB make them even able to boot on Linux:

ivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1
and 
spec_store_bypass_disable=on or spec_store_bypass_disable=seccomp

Otherwise Linux does not boot.

Thanks to evilazrael who found that workaround, otherwise still no-one would be able to boot a Linux distribution on the laptop.

The initial analysis from him you find here:
https://evilazrael.de/node/401

An ongoing discussion of the case you find here:
https://forums.lenovo.com/t5/ThinkPad-11e-Windows-13-E-and/ThinkPad-E485-E585-Firmware-bug-ACPI-IVRS-table/m-p/4191484

It would be nice if it would be fixed, because many user will relinquish using Linux if it does not boot on the first time, and also all others users need a fix, because the workaround may reduces performance and increases power use.

The issue doesnt lie within the kernel .config, i compiled a gentoo kernel with archlinux vanilla .config and i could still boot without parameters.

The question is what is in the config that causes everything to work. Even
a vanilla config can possibly match the Gentoo config in an option that
fixes ACPI.

Comment 89 siyia 2019-01-26 08:37:46 UTC
The problem with these acer laptops seems to be that the "flat" APIC mode is used instead of "physical flat".With "physical flat" model acpi works fine and acpi tables seem to load successfully, you can later optionally remap the ivrs tables without hanging.Would it be possible to have a switch like a kernel parameter that skips autodetection of APIC model and let us choose the preffered one?
Comment 90 Darksurf 2019-01-26 16:12:06 UTC
Well, autodetection does appear to work so long as the appropriate settings are detected or already set. REMAP_IRQ was the missing option for Sabayon that allowed physical flat to occur after mapping missing IVRS data in grub commandline otherwise I had to use noapic before enabling this. I must admit though, that finding out about this option was rather difficult since its not triggered by the user, but by the selections already chosen in the kernel.

Comment 93 Another User 2019-01-30 13:59:06 UTC
Are these (other than noapic) workarounds really enable APIC controller? With acpi=noirq only PIC and MSI entries present in /proc/interrupts. So I assume acpi=off does the same. While noapic obviously disables APIC but works fine for me.
Looks like ivrs_ioapic... enables APIC, but in my case system is very slow and even not always boots.
Is disabled APIC have significant drawbacks (while most of devices placed on MSI-routed PCI lanes)?
Comment 94 siyia 2019-01-30 14:07:46 UTC
I dont think so, but with noapic i think only 13 aml tables load instead of the 14 available,so you might get acpi problems with suspend/resume or cpu powersave features(at least that's what i get).Try running gentoo or calculate linux and test acpi and apic.Ideally "physical flat" apic model chosen by kernel config of those distros works fine in my case and all 14 aml tables load.

Comment 97 nyxone 2019-03-15 12:56:07 UTC
A315-41 with BIOS 1.13 and kernel 5.0 has the same behaviour as before, IOAPIC tables are missing the two entries. The CPU stuck problem still occurs unless you specify the grub parameters specified in threads above. Also the battery has the same drain rate. It may worked for siya somehow but the bug is still present and should not be closed.
Comment 98 siyia 2019-03-15 13:23:26 UTC
ivrs tables are missing for me too but i do not get the cpu stuck error anymore, also cpu powersave and acpi works on kernel 5.0 with bios v 1.13. I optionally remap the ivrs tables after linux installation just to remove the warnings, however my laptop model is A315-41g not A315-41.

And touchpad behaviors somewhat strange. It forced to advanced mode in 1.03 bios too, but does not cause suspend issues - sleep by Fn+F1 works fine.

@Darksurf i looked at that laptop model and there was an 1.12 bios for it but the changes wasn't that exciting.

"1.Add SCCM solution.
2.Change touch pad mode from basic to advance for linux sku."

So it looks like my changes in 1.12 got merged into everyone's 1.13?  it's
an obvious attempt at some form of Linux support. BIOS tweaks don't have to
be exciting or glorious to show they're trying vs ignoring us. It's baby
steps in the right direction. They also don't breakdown the exact changes
making the changes seem vague and unexciting. Not much in the way of
details.

I think acer should join the Linux Foundation or sth, this is embarassing, they cant even create proper iASL compliant bios.
Comment 114 bakarichard91 2019-03-18 18:40:24 UTC
siyia, I don't think they created it. Firmwares are often manufactured by third party companies however it would be nice to see a studious community work.

A315-41-RX8R here. With 1.13 still cannot boot into manjaro default 4.20 kernel without ivrs_table\noapic tricks. CPU soft lockup
Comment 116 Vladislav Kamenev 2019-03-19 20:59:00 UTC
Soft lockups now occurs even with ivrs_table arguments in place.
Comment 117 Vladislav Kamenev 2019-03-19 21:02:21 UTC
After update to 1.13 my touchpad doesn't work in Linux. Not recommending
Comment 118 Vladislav Kamenev 2019-03-19 21:21:50 UTC
Manjaro 5.0.2 kernel can start without exotics with 1.13 bios. Wi-Fi firmware(ath10k), however, dies right after getting into DE. Interestingly - vulkan bugs with Vega 8 went away with this update. Hibernation works (but unbelievable slow and artifacting while processing). TurboBoost after hibernation works. WI-FI ressurected after waking up from hibernation.
Comment 119 siyia 2019-03-20 04:11:21 UTC
to revive touchpad after 1.13 do:

sudo modprobe -r i2c_hid
sudo modprobe i2c_hid

as for the wireless problem i ve opened a back report here:

Running a 2200U with Bios 1.13 and Kernel 5.0.3, and I still soft lock without pci=noacpi in grub before boot. Fan definitely is running at 100% after booting as well. With pci=noacpi, I can boot, but the touchpad does not work, although I haven't attempted to work on that problem yet.
Comment 124 siyia 2019-03-21 19:31:39 UTC
Ness are you using secure boot?
Comment 125 siyia 2019-03-21 19:32:53 UTC
your fan runs at 100% because you use pci=noacpi

Yep still get hard lock if I don't add both missing IVRS table data for
0:00.2 and 0:14.0 . But, I no longer require i8042.nopnp to get touchpad
working, but it does complain about an AUX port being disabled and if it's
incorrect it says to use i8042.nopnp. tested with Git

Comment 127 bakarichard91 2019-03-26 13:55:04 UTC
There should be some improvement because using the new BIOS, the suspend-resume cycle works much better for me. 41G

Darksurf you have that proper Acer support contact where they tried to help you/us. Would you not like to send them a lovely mail asking if they could delegate a little team for Linux kernel support/development as the biggest Notebook manufacturer in EU and one of the biggest in the USA. This should be a must have.

What blows my mind is they used Linpus Linux (fedora spin) for specific
laptops that come default on the laptop. They surely already have a team, I
don't they write their own BIOS which appears to be the problem to me.
Missing data in the IVRS tables is the only issue I have. Otherwise
everything works great. I can try to locate the contact and send him
another email to let him know the situation has improved, because I too
seems to have great suspend resume support now after the BIOS update. Maybe
the correct thing to do would be complain to linpus.com support?

Comment 129 bakarichard91 2019-03-26 22:19:21 UTC
Both way worth a try. You could be right about Linpus, we should figure out where is the team which patched linpus kernel for these notebooks.
Comment 130 Vladislav Kamenev 2019-03-27 10:32:15 UTC
Updated kernel from 5.0.2 to 5.0.4 and now i'm getting hardlocks on boot. On 5.0.2 i could boot without any special kernel arguments
Comment 131 Vladislav Kamenev 2019-03-27 11:15:04 UTC
LoL downgraded kernel back to 5.0.2, which i considered OK and still i cannot boot into system without special arguments, like i did before when 5.0.2 was latest in repos. Seems like some other package broke my experience.
Distro: Manjaro

You won't believe me. When i have mouse usb plugged in usb 2.0 that near power plug - my boot is OK. When it is not - hard lockup on boot
Comment 134 siyia 2019-03-27 12:03:42 UTC
only that port works and you dont lockup?second usb2 port?
Comment 135 Vladislav Kamenev 2019-03-27 12:07:00 UTC
Or i'm very lucky and this is coincedence or yes, when my mice is connected (doesn't have other usb devices at the moment) to usb 2.0 that is nearest to power plug my boot is successfull without any special kernel arguments.

Comment 144 Kung Lao 2019-04-05 19:24:32 UTC
Something doesnt sound right here, it's been over a year that this problem is known and nobody from AMD team commented on this, not even that they are working on it. Now out of a sudden one of their engineers claims they solved it but doesnt attach any kernel patch or info on the issue, just marks it as fix released. Another thing that is weird is that we are almost sure its a BIOS issue according to posts above, so this "fix" might be the same thing that ivrs kernel options do.
As for the issue you can verify its existance by the buzzing sound that power components do on the Acer's mainboard when ACPI doesnt work like it should. At Windows 10 the buzzing sound if you take close attention exists where the power management works correctly.

Comment 146 Kung Lao 2019-04-05 19:40:37 UTC
Thanks for the informative paste Richard, sorry for my frustration but for most of us the waranty of the laptop is almost expired and the issue still exists.
Comment 147 bakarichard91 2019-04-05 19:49:18 UTC
Kung Lao, the market share of Linux desktop is very low so supporting it hasn't got high priority, unfortunately. However the manufacturers should be more flexible because of the future opportunities.
Comment 148 siyia 2019-04-05 20:02:57 UTC
Market share cannot be an excuse in this case, i've read myriad reviews about lenovo-hp-asus laptops that either worked out of the box with linux, or had a quick bios fix that resolved the issue, acer is just sloppy and lazy.They dont have to support linux directly, but at the very least they could make their bios iasl compliant in order to work with the acpi spec.
Comment 149 Kung Lao 2019-04-05 20:12:09 UTC
Siya market share defines the percentage of workers that get assigned to each problem. So even though Richard is correct that fewer people use Linux on their Acer laptop it still is false-advertising to sell Acer laptop with linux preinstalled when the only thing that boots is their ancient and ultra rare distro. I also noticed from what someone mentioned above that fixes start from flagship models and find their way to the lowest tier. We are probably lucky that same components and BIOS were used with expensive models.
Comment 150 bakarichard91 2019-04-05 20:12:44 UTC
That is not clear if their bios should meet the standards or not. It's also not clear if we should accept that they support Win10 only. I don't really know.

Maybe this is something which is relate to this. What do you think?

Comment 151 siyia 2019-04-05 20:18:33 UTC
Yea, well said, i spent 400 euros for this acer laptop and it came with linux pre-installed(as an average consumer i thought that this meant linux is supported out of the box), at least they try to fix the issue, but already a year has passed and the results from many bios updates are mixed.If anyone considers buying an acer laptop in the future and want to run linux, isuggest read a review first before buying, because things like these can get really frustrating.
Comment 152 siyia 2019-04-05 22:03:42 UTC
Anyways i am curious, do these laptops work with freesync?anyone tried it?
Comment 153 Erik 2019-04-10 10:53:06 UTC
With bios/UEFI 1.13 and kernel 5.0.7 things seems to work.
I got touchpad working by installing https://github.com/Syniurge/i2c-amd-mp2 (master works, the wip-v16 doesn't work and screwed up a lot of things when i tried it so don't try that version).

git clone https://github.com/Syniurge/i2c-amd-mp2.git master
mv master i2c-amd-mp2
cd i2c-amd-mp2
LANG=C sudo ./dkms-install.sh

First i booted with pci=noacpi and with that touchpad wasn't working with bios 1.13 that uses advanced touchpad, it did work with earlier bios that had basic option for touchpad.
Removing pci=acpi and instead using:
ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
did the trick for me.

I sometimes needs to toogle wifi after suspend, i haven't tried hibernate.
My laptop is an A315-41 non G but it think the G only means that it also has a dedicated graphicscard.
I haven't tried it out much yet but at least things seems to work now.
Comment 154 Erik 2019-04-10 11:12:56 UTC
I forgot to add that some distributions may include i2c-amd-mp2 built in to the kernel and that may be an older non working version.
If that's the case then you need to rebuild the kernel without the patched i2c-amd-mp2 support and then you can add i2c-amd-mp2 as i posted in previous post.
I compiled an non patched vanilla kernel with a custom .conf and then added i2c-amd-mp2 support.
It do work with an non patched vanilla kernel, some distributions patches the kernel so much that i may be the reason that things doesn't work.
Comment 155 kgs 2019-04-10 13:28:41 UTC
"Things seem to work" is a bit confusing here. Can you boot without any parameters? Because it worked with parameters before the bios/kernel patches..
Comment 156 Erik 2019-04-10 15:12:35 UTC
As i wrote i still use parameters.
ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
For me i couldn't boot with anything other then pci=noacpi before, but now ivrs parameters work and i got a working touchpad.
"Things seem to work" is because i have only used the laptop for a day and i haven't tested every single scenario, but as far as i can tell it works.
I wasn't able to boot with ivrs parameter before and i had no use of the laptop that was only useful as an paperweight, it couldn't suspend or hibernate. 
Now i have a working laptop that i can finally use and no fans going berserk.
Comment 157 Michael T 2019-04-11 07:19:27 UTC
A315-41 booted with ivrs_ioapic kernel settings since kernel 4.18, nothing new here. Also with ubuntu 19.04 beta the touchpad works without any tricks or custom kernels. The problem is the battery draining fast and rare freezing. We are waiting for the promised fix from AMD.
Comment 158 Erik 2019-04-11 16:17:35 UTC
Maybe it worked with kernel 4.19 with your distribution but touchpad didn't work for me since i only use vanilla kernels without patches.
Ubuntu patches i2c-amd-mp2 support, in older kernel series there was an older version that didn't work for many laptop users that needed to recompile the kernel without that module built in and add the support later, but maybe it works with A315-41 laptops.
In later ubuntu kernels series the i2c-amd-mp2 support is built as a module =m instead so it can stopped from loading, in 4.19 it's still compiled into the kernel =y for both x86_64 and i386 in the kernel config but in 5.0 it's compiled as a module =m for x86_64 but not at all for i386 (source https://kernel.ubuntu.com/~kernel-ppa/mainline).
If that patched support makes your touchpad work good with ubuntu then good for you but not everyone is a ubuntu user.
For vanilla kernels the touchpad support is supposed to land in mainline in kernel 5.2.

It's very easy for people using certain distributions to think that because something works that it's works for everyone, not taking into account the distributions extensive patching and fixes everywhere but also hardware variations.
I use vanilla kernels not patched ones.
I just tried a non patched 4.19 kernel with those options and it did boot, i was also able to get touchpad working with dkms i2c-amd-mp2, so things seems to work with 4.19 as well.
If your distribution use patched kernels you might have had some support with earlier kernels, not because of the linux kernel but rather your distributions patches, so kernel updates might be different with different distributions or if you use a vanilla kernel.

Battery draining, i don't have any drainage battery problems that i am aware of, yesterday i used my laptop for 3 hours on battery, working, looking some youtube, some video from hdd and 25-30minutes of compiling.
I think that the battery uptime is acceptable and i got almost 3h with 4.19 as well but then i didn't compile anything.
I got no idea how long the battery should last but 3h seems ok to me.
How fast do your battery drain?
Comment 159 Michael T 2019-04-11 19:51:06 UTC
Erik you'd be surpised to know that many people don't use vanilla kernels or don't have special knowledge on linux. It's OK to give details and github patches but it gives the false impression to people who just search their problem, that their 
touchpad won't work out of the box.

Ubuntu is not "my distro" is one of the top distros and many projects use it as a proposed base to build like AOSP , Chrome browser etc. It wasn't hostility against you so your defensive stance is unreasonable.

To the battery draining part, I get almost 5 hours with Windows 10 testing and many people commented that this the ultimate goal :) Because you asked about my drain I got 2h40m max watching youtube and IRC talking as I remember.

A fix is prepared so it means THERE IS a problem. Cheers mate.
Comment 160 siyia 2019-04-11 19:53:35 UTC
I dont know what you people are talking about 5hrs of battery life on windows, but on all my budget laptops that run linux i get a max of 3hrs.
Comment 161 Michael T 2019-04-11 20:04:02 UTC
If you check the manufacturer specifications, at least for my model it says "Maximum Battery Run Time 6 Hour" ofc this is not realistic, but 5h is. I'm not saying that different OS's should have the same energy behaviour but going from 6h -> 5h -> 3h and less as the battery material degrades is not good. I'm not expert in linux internals but I kept open the CPU usage graph in both windows and linux, and while the percentages were very close with same usage the draining was faster. I didn't put a CPU frequency graph though and I suspect the problem is there, that linux doesnt put it in the lowest needed freq scale when not needed.
Comment 162 bakarichard91 2019-04-11 21:35:00 UTC
For better battery time in linux set the cpufreq governor to "powersave" and check powertop options.
Comment 163 Kai-Heng Feng 2019-04-12 14:16:51 UTC
The latest i2c-amd-mp2 driver will be included in next Ubuntu Bionic, Cosmic and Disco kernel release.
Comment 164 Erik 2019-04-12 19:39:55 UTC
I just tested battery time in windows, with full brightness as i had in previous tests and i was able to get about 15 extra minutes from windows 10, my guess is that's because windows forced a power save mode when there was under 20% left of the battery charge. 
There was no compilation in windows.
I didn't see any major difference but i didn't test settings for maximum battery uptime on any of the OS tested.
I used "ondemand" in linux as it was default setting and also default in windows with the only change being full brightness.
I will try different brightness settings in linux to see how it affects battery uptime.
I don't see anything pointing to an battery drainage problem.

@Kai-Heng Feng is that v15 of the patch series?
Will it be compiled into the kernel or as a module?
Comment 165 bakarichard91 2019-04-12 19:57:18 UTC
Erik, try that what I wrote. Powersave mode + powerop (enable all powersave settings)
Comment 166 bakarichard91 2019-04-12 19:59:11 UTC
Erik, try what I wrote: powersave option + powertop settings enabled.
Comment 167 Michael T 2019-04-12 20:37:32 UTC
Windows 10 when installed and at first day(s) make a lot of tests for system health and configuration, especially when idle, even .NET compilations. Another factor is the edition you use with/without store and universal apps that run in the background. Most of all you need to use the power profile that Acer provides. Do you have the model with SSD, do you have the extra GPU model, do you use high/low brightness... For me Windows 10 give almost 5 hours max but average use 4 1/2 maybe. I compared with Ubuntu default settings and low brightness with same hardware and got almost 3 hours battery time.

Richard I haven't tried yet the powersave settings, I will wait for the final release of 19.04 to re-install it on my hard disk.
Comment 168 Michael T 2019-04-12 21:06:17 UTC
Eric I compare optimized Windows 10 with the bare minimum options and configured for energy saving rather than performance. Since I'm not good at linux I can't do the same there to have an accurate result. This feels like testing apples with oranges but still is the most I can do. I will try Richard's settings and see... Sorry for getting out of subject for everyone who reads.
Comment 169 federico 2019-04-13 14:48:30 UTC
I'm using Elementary OS 5 on Acer Aspire A315-41 with kernel 5.0.7 and the workaround indicated by Erik (#156). After the workaround everything worked well but noticed a strong battery drain.

Installed tlp, restarted the machine and the battery lasts around twice as much, comparable to a windows machine. I can say it solved the battery issue for me.
Comment 170 Vladislav Kamenev 2019-04-13 15:02:42 UTC
Manjaro 5.0.2 kernel here. As i reported before most of my bootings w\o any kernel parameters are fine, but today i found out that my 2500u won't boost any further 2.0ghz. Idk whether it caused by sleep or my cpu was like that right after boot sequence. I used to write ivrs_table argument with 4.20 kernel and then sleep\hibernation went off, but CPU were boosting up to 3.6 ghz as supposed to.
Comment 171 Vladislav Kamenev 2019-04-13 15:03:27 UTC
tl;dr even if it would be possible to boot without any tricks in kernel arguments some features of cpu would  still be borken
Comment 172 Vladislav Kamenev 2019-04-13 18:40:46 UTC
So, manjaro 5.0.7 boot with this cmdline

CPU doesn't boost itself any further than 2.0 ghz. Gonna check 5.1-rc4 with AMD fixes later
Comment 173 siyia 2019-04-13 18:47:40 UTC
try running mprime to check cpu frequency scaling,mine could run at 3.6ghz and after i disable turbo boost runs max at 2.5ghz

Turns out my iommu was disabled in bios. I turned it on and ivrs mapping fixes all the issues for me.
Comment 181 siyia 2019-04-13 19:50:26 UTC
you see you shouldnt panick right away, secure boot also causes suspend\hibernation issues for me so if you have further problems disable that too.
Comment 182 Vladislav Kamenev 2019-04-13 19:59:24 UTC
I don't need to map ivrs to boot 5.1 successfully 100% times. Seems like you need to have secure boot disabled (i did it like last summer) and iommu ENABLED (my laptop comes with it disabled cuz i only have 1 gpu integrated in CPU). 
Please confirm that 5.1 boots for you without any tricks without any issues
Comment 183 siyia 2019-04-13 20:12:54 UTC
i can boot latest 5.0 with no parameters in manjaro, i bet i can boot 5.1 just as well,i am not willing to download and try an in-development kernel right now.
Comment 184 Erik 2019-04-16 10:16:58 UTC
@Vladislav Kamenev i still need ivrs to boot 5.1-rc5 kernel.
Since there was talks about problems with hibernation i even setup a swap file and tested hibernation (Suspend to Disk S4) and it works, i normally only use suspend (Suspend to RAM S3), suspend works with all my kernels 4.19+ and ivrs.

Could you please check secure boot and iommu settings in bios?
Comment 186 Erik 2019-04-16 11:08:37 UTC
I have IOMMU and SVM enabled in bios/UEFI.
I toggled Secure boot setting and it doesn't change anything, hibernation works anyway and i still need ivrs to boot.
I tried with secure boot enabled and hibernation works with all my kernels (4.19.34, 5.0.7, 5.1-rc5).
Since i use a swap file for hibernation i did have to add boot parameter resume= and resume_offset= but i doesn't count those since they are only for hibernation with swap-file.
I do have my grub added as a trusted boot if it changes anything.
In earlier bios version i wasn't able to boot with secure boot disabled unless i added it as trusted first, my guess is that it was because off a buggy bios/UEFI.
Comment 187 Vladislav Kamenev 2019-04-16 11:10:15 UTC
Have you updated bios to 1.13?
Comment 188 Erik 2019-04-16 11:47:34 UTC
Yes i got bios 1.13.
The bug with being forced to add my grub as trusted file was in earlier bios and i don't know if it's still in the latest bios as i haven't tried it out.
Comment 189 Erik 2019-04-16 11:48:50 UTC
I got the non G model (no dedicated GPU) A315-41.
Comment 190 siyia 2019-04-16 14:16:49 UTC
The problem with suspend/hibernation was with usb3 port not secure boot, just disable wake from usb devices at xchi0 and xchi1  controllers.
Comment 191 bakarichard91 2019-04-21 03:27:47 UTC
Dear kernel developers,

the ACPI seems to be OK from kernel v 5.1 but only with using the ivrs_ioapic kernel parameters. This is almos a constant failure by these notebooks. Couldn't this be hardcoded somehow into the kernel?
This bug is almost one year old and we know how it can be fixed but we are not kernel developers to make/create the proper patch.

Could you please help us?

Thanks,

Richard
Comment 192 kgs 2019-04-21 07:04:20 UTC
I'm not sure hardcoding them would be so good - I was getting a performance hit when using the ivrs_ioapic params. Now I'm using these ones suggested in the other thread and everything works better for me: https://bugs.launchpad.net/amd/+bug/1776563/comments/445
Comment 193 bakarichard91 2019-04-21 08:30:12 UTC
These don't work for me. I don't think ivrs_ioapic causes performance loss. Why it should? Show me a dmesg!

Do you use any other options or overrides?
cat /proc/cmdline
What kernel works for you with only acpi_osi="Linux"?
What does your dmesg look like?
I have previously tried acpi_osi="Linux" with bios/UEFI 1.13 and had no luck with it.
Comment 197 logxx 2019-07-03 11:35:40 UTC
repeating myself, cuz launchpad sync lags:
well, i haven't used any other options, it works with kernel 5.1.14, dmesg still complains about missing entries and iommu perf writing
Comment 198 bakarichard91 2019-07-03 12:13:11 UTC
I think this problem has been verified because it affects many people.

[SUMMARY]
Kernels (even the newest) can't load on same Acer and Lenovo notebook types because of this error and freezing:
https://bugzilla.kernel.org/attachment.cgi?id=276591
Tsc clocksource calibration then soft lockup

There are several workaround for this which can help to identify this.

1. noapic kernel parameter
2. ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
(these are maybe the smbus and iommu controllers )
3. acpi_osi=! acpi_osi=\"Windows 2009\"
(no automatic stanby mode with this)


I can attach more recent dmesg logs and even SSDT DSDT tables if that is needed.

I think all necessary information are available to fix this problem, so !!!PLEASE DON'T SPAM!!! this thread from now on. It won't help.

Comment 204 Suravee Suthikulpanit 2019-07-16 15:11:57 UTC
For IOMMU-related part, as mentioned above, the IVRS table does not list the correct IOAPIC IDs. This would cause driver to disable interrupt-remapping support provided by HW IOMMU.
Here the "ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2" boot option is needed to override the table. Permanent solution would be for laptop OEMs (e.g. Acer, Lenovo) to fix this in their BIOSes.

Another alternative would be:
* Disable IOMMU in the BIOS (which should also get rid of the IVRS table)
* Disable HW IOMMU and use SWIOTLB for any DMA-remapping (iommu=soft)

However, I'm not sure about why the "noapic" option is needed.
Comment 205 bakarichard91 2019-07-16 15:23:28 UTC
Hi Suravee Suthikulpanit,

Thank you for the reply.
noapic is not needed, that had been just a worse option before we found out the ivrs option.

So you say this can not be fixed in kernel permanently. I would be happy if no kernel parameter was needed. Many people don't know about this, especially beginners who just want to use fe.: Ubuntu.

I don't think manufacturers will fix this.

You are here the only one who can give us hope.

Is it possible to use DMI based quirk to override the tables?
Comment 207 bakarichard91 2019-07-17 14:53:41 UTC
Or in this cases why does the kernel not find the pci "devices" somehow like we do?
Comment 208 logxx 2019-07-23 14:43:49 UTC
Have just installed arch linux with kernel 5.22 with ivrs parameters. After that, it loads without any parameters! Maybe it's because of amd-ucode that i have also installed, but i am not sure. I haven't install GUI yet, so i'll investigate further

Ironically, my Acer A315-41 ships with IOMMU disabled by default (maybe because its a modification w\o dGPU) and i got rid of soft lockups by explicitly turning it on in BIOS

After I had installed the new bios from Acer support site the kernel loaded with and even without ivrs kernel parameters however the GUI didn't start if I used the ivrs parameters.
Could somebody confirm this?

So the new bios cuold be a fix for this issue.

For the grub lagging, try this:
sudo nano /etc/default/grub
GRUB_GFXMODE=1280x800
sudo update-grub

If this doesn't fix it you can try another resolutions.

Comment 223 Erik 2019-08-21 14:56:16 UTC
I have now upgraded to bios v1.15 and everything seems to work as expected and i don't need to override IVRS anymore.
I couldn't replicate the slow boot loader, tried grub 2.04 and elilo and both was working as fast as always.
This bug is finally fixed in bios update.

I used windows to upgrade bios.
Didn't suspend work for you before?
I been using suspend and hibernate for a long time, well i almost never use hibernate but last time i tried it did work.
Is grub and bios real slow and sluggish or usable?
Comment 227 logxx 2019-08-21 20:35:19 UTC
Under KDE, suspend doesn't work with recent kernels, see https://bbs.archlinux.org/viewtopic.php?id=247761, the BIOS is usable, but grub feels a lot slower than it was

I was trying another kernel parameters and noapic seems to work. It is not needed to disable the whole ACPI "service" https://www.icrwatch.com/
, however I don't know how important apic is. On kernel 4.18 even temperature sensors appear.

You should update your bios to v1.15 after that you don't need any overrides.
After that you can remove the noapic since it isn't needed.
