Description Chris Murphy 2014-06-30 22:49:57 UTC
Message appears most every boot. With irqpoll set, the trackpad isn't responsive and sometimes the keyboard isn't either although those could be related to other rawness in Rawhide.

This is not a new problem, it's been present since at least kernel 3.6.11 on this same hardware model.

photo trace with acpi=noirq

With acpi=noirq I get something akin to a panic. Still model MacbookPro 8,2.
Comment 6 Chris Murphy 2014-07-02 01:16:20 UTC
On the MacbookPro 8,2, the message doesn't happen (or happen as often) if I use b43-fwcutter to copy firmware to /lib/firmware. The message still occurs on a 9,2 model even with firmware in /lib/firmware.

I am also experiencing the same problem with MacBook Pro Early 2011 Model.
Please take a look at bug https://bugzilla.redhat.com/show_bug.cgi?id=1149632
Thanks.

Looks like irq 17 is attached to mmc card controller.

Comment 16 Dan Ziemba 2014-12-26 23:28:03 UTC
Same problem here on my macbook pro 8,1.  Currently with Fedora 21, kernel 3.17.7-300, but has existed for at least a couple years with previous fedora versions.  I have the b43 module blacklisted because I use an external usb wifi instead (Atheros AR7010+AR9280), so maybe this can rule out the wifi being related?  Here's part of the log from my last boot:

Dec 26 14:10:48 fedoramac kernel: Disabling IRQ #17
Comment 17 Christian Stadelmann 2015-03-21 13:34:33 UTC
This bug does not only happen in the MMC/SD card stack. I am running into this bug on a Asus P7H55-M/USB3 board with just 2 USB devices (mouse and keyboard) and no card reader installed. Still libreport tells me it is the same bug as https://bugzilla.redhat.com/show_bug.cgi?id=1149632

In my case it is IRQ 16 (not IRQ 17) that's affected. On this IRQ 16 I have 2 devices according to `$ lspci -v`:

00:1a.0 USB controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 06) (prog-if 20 [EHCI])

        Kernel driver in use: pcieport
        Kernel modules: shpchp

Both devices are part of the Intel H55 chipset.
Comment 18 Chris Murphy 2015-03-23 14:15:21 UTC
Always happens with these kernels as well, regardless of whether the b43 firmware is in /lib/firmware.

Comment 19 Chris Bainbridge 2015-03-29 11:53:44 UTC
It looks like this bug has been around for years. There is a report from 2011 from a user of linux kernel 3.1.1: "Unless the bcma and b43 modules are compiled and loaded, IRQ17 is shut early in the process." https://dentifrice.poivron.org/laptops/macbookpro8,2/

I have confirmed the bug is still present in linux 3.16.0-4 and latest linux 4.0.0-rc5+ 7fc377e on a 2012 Ivy Bridge Macbook Pro 13.

mmc0 and b43 share interrupt 17. The bug happens when the sdhci module is loaded before b43. If b43 is builtin or loaded in initramfs (/etc/initramfs-tools/modules, update initramfs) then this bug will not occur.

Comment 20 Chris Bainbridge 2015-03-30 14:52:45 UTC
@Christian Stadelmann - Your bug looks like a different one. This bug report is for the boot error "irq 17: nobody cared" from Broadcom BCM57765 card reader (as used in Macbook Pro) as described at https://lkml.org/lkml/2013/7/12/99
Comment 21 Christian Stadelmann 2015-04-07 08:34:25 UTC
@Chris Bainbridge - I don't even have a broadcom card reader in this computer. It might be unrelated though.
Comment 22 Chris Bainbridge 2015-04-07 09:41:09 UTC
There is also bug #73241 - SDHCI PCI driver incompatible with 14e4:16bc / Broadcom BCM57765/57785 SDXC/MMC Card Reader
Comment 23 Scott Corcoran 2015-10-30 06:21:19 UTC
This "irq 17: nobody cared" boot crash was repeatable together with
a variety of other minor failures booting MacBookPro8,2/Mac
3.8Gb, Intel Core i7-2860QM @2.50GHz x 8

Interestingly, the co-installed RESCUE system
4.0.4-301.fc22.x86_64 #1 SMP came up and ran just fine.
Not sure what the differences between the systems are.

[PATCH] PCI: Add Broadcom 4331 reset quirk to prevent IRQ storm

Here's a patch to fix this issue, please test if it works for you. It does for me.

This bugzilla entry is misclassified as an MMC/SD bug because the kernel error message makes it appear that sdhci_irq is the culprit. That's a red herring, the issue is caused by an IRQ storm originating from the wireless card.

What seems to be happening is that Apple's EFI bootloader enables the wireless card to use it for Internet Recovery and it leaves the card enabled when passing control to the OS. The card cries for attention by sending interrupts, interfering with other drivers using that same IRQ line. This does not stop until the wireless driver is loaded. The patch resets the card early on in the boot process to stop the interrupts.

Trying your patch on the Debian and kernel 4.4.10 sources It did not help for me.

Messages continue in dmesg "irq 17: nobody cared" and irq storm is continuing.

Besides messages in dmesg, as before i get to become unstable wi-fi, every hour randomly disconnects occur.  I use last a proprietary broadcom driver 6.30.223.271 (Use b43 driver does not change anything) Also lost connection for a minute or a little less dmesg reports this "ERROR @wl_notify_scan_status: eth1 Scan_results error (-22)" (my wlan name eth1 :))

Yes I've heard that the patch doesn't work for everybody. I don't know why, perhaps DisINTx is not set on the wireless card on some machines upon boot. To verify that's indeed the cause, boot with "modprobe.blacklist=b43 modprobe.blacklist=bcma modprobe.blacklist=wl", then check if "lspci -vv" reports "DisINTx-" for the wireless card.

I've attached two alternative patches. They cannot be submitted as is, they need more polish, but I can't decide which one is better. Please test both and let me know if either or both work for you. They're based on 4.4 but can be applied to 4.6 as well with some fuzz.

b43_eboot_4.4.patch resets all network interfaces before control is handed over from EFI to the kernel. This only works if you boot with the EFI stub. If you use gummiboot, the EFI stub is used by default. If you use grub I think you have to load the kernel with the "chainloader" directive, not the "linux" directive. You should briefly see a message "Welcome to Macintosh" on boot, plus the line "Resetting network interface" for every network card built into the machine.

b43_earlyquirk_4.4.patch resets the BCM 4331 card during kernel initialization. In dmesg there should be a message "Resetting Apple AirPort card". If MMIO was not already enabled, you'll see an additional message "Enabling mmio on Apple AirPort card". Let me know if you see that additional message as I'm not sure if I should drop this, maybe MMIO is always enabled and this is not needed.

I'm not sure if this is a bug in the EFI driver for the BCM 4331 or if this is actually a feature. Perhaps OS X supports some kind of connection handover from EFI. If this is true, it's not sufficient to just quirk the BCM 4331, we'd need this for all other cards used by Apple. E.g. models introduced 2013+ use BCM 4360. The eboot patch works for all cards whereas the earlyquirk patch re

Yes I've heard that the patch doesn't work for everybody. I don't know why, perhaps DisINTx is not set on the wireless card on some machines upon boot. To verify that's indeed the cause, boot with "modprobe.blacklist=b43 modprobe.blacklist=bcma modprobe.blacklist=wl", then check if "lspci -vv" reports "DisINTx-" for the wireless card.

I've attached two alternative patches. They cannot be submitted as is, they need more polish, but I can't decide which one is better. Please test both and let me know if either or both work for you. They're based on 4.4 but can be applied to 4.6 as well with some fuzz.

b43_eboot_4.4.patch resets all network interfaces before control is handed over from EFI to the kernel. This only works if you boot with the EFI stub. If you use gummiboot, the EFI stub is used by default. If you use grub I think you have to load the kernel with the "chainloader" directive, not the "linux" directive. You should briefly see a message "Welcome to Macintosh" on boot, plus the line "Resetting network interface" for every network card built into the machine.

b43_earlyquirk_4.4.patch resets the BCM 4331 card during kernel initialization. In dmesg there should be a message "Resetting Apple AirPort card". If MMIO was not already enabled, you'll see an additional message "Enabling mmio on Apple AirPort card". Let me know if you see that additional message as I'm not sure if I should drop this, maybe MMIO is always enabled and this is not needed.

I'm not sure if this is a bug in the EFI driver for the BCM 4331 or if it's actually a feature. Perhaps OS X supports some kind of connection handover from EFI. If that is true, it's not sufficient to just quirk the BCM 4331, we'd need this for all other cards used by Apple. E.g. models introduced 2013+ use BCM 4360. The eboot patch works for all cards whereas the earlyquirk patch requires a list of all cards used by Apple. So that's an advantage of the eboot patch. *If* this is indeed a feature, which I don't know.

A disadvantage of the eboot quirk is that it only works if the EFI stub is used. So I have no idea which patch to continue working on. If only one of them works for you, that would certainly make the choice easier.

Testing b43_eboot_4.4.patch patch will take longer. because it is i currently having problems with grub2 loading the kernel in EFI stub. To reading manuals will take some time.

I decided to spend a little experiment. I am physically disconnected conbined Broadcom BCM94331 module from the laptop motherboard. and I got a strange result, message "irq 17: nobody cared" gone, but this:

Who sending interrupts gpe17 if wi-fi physically not present in system? Thats normal situation or not? May be it may be something i do not understand?

I've just realized, since you're using Debian it might be sufficient to just replace "linux" with "linuxefi" in your grub configuration. The Debian grub2 package carries a patch to enable this command:

http://lists.gnu.org/archive/html/grub-devel/2014-01/msg00137.html
https://anonscm.debian.org/cgit/pkg-grub/grub.git/commit/?id=e4951626e0ab33c446cfd7e9a22044f602ca0106


Obviously resetting the card didn't work with b43_eboot_4.4.patch, the lspci output shows "INTx+" in the "Status:" line, so the card keeps asserting its interrupt line. Question is why. Michael Büsch mentioned on linux-wireless@ that my patch only works if the wireless core is the second one on the card. On my machine that's the case, but perhaps your machine uses a different revision of the chip with a different layout. If you try "modprobe b43", which cores does it list in dmesg?

On my machine it looks like this:
[   59.706481] bcma: bus0: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x25, class 0x0)
[   59.708383] bcma: bus0: Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x1D, class 0x0)
[   59.710324] bcma: bus0: Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x13, class 0x0)

If the core labeled "IEEE 802.11" has a different id than "1" (i.e., it's not the second core), that would explain why the patch isn't working on your machine.

GPE 17 is used by the ACPI Embedded Controller, apparently it's unhappy if the wireless module is disconnected. There's an I2C bus between the EC and pins 12 and 14 of the wireless module connector which I believe is used for a temperature sensor, perhaps the EC fires its interrupt because it thinks that something on or near the wireless module is overheating. Also, pin 10 is used to signal wireless events (Wake on Wireless LAN perhaps), the pin goes to low (!) when an event occurs, so by disconnecting the card I guess it signals an event all the time.

I would like to say that the situation gpe17 does not change, if the card is connected or not connected. It seems rather strange, can may be faulty hardware controller cardreader?
Comment 35 hr 2016-05-15 12:35:19 UTC
I was not able to get the kernel boot efi stub on grub2. Linuxefi settings work, but I always get a kernel panic, as the kernel can not find the file systems. I even tried to build into the kernel cmdline option indicating the partition UUID but something I'm doing wrong and it does not work.

Finally install rEFInd, it loads the kernel without any problems. your patch b43_eboot_4.4.patch work early in the boot there are lines Welcome to Macintosh, and two lines "Resetting network interface"

Error "irq 17: nobody cared (try booting with the" irqpoll "option)" is no more.

But now the system hangs during operation minutes or slightly less if there sometimes is used Internet application (no response to the cursor does not react to pressing the keypad). Of course, I can`t see dmesg, all I can do is clamp the power button on the laptop to turn it off and on again. If wl driver is not loaded, then there is no hang-ups.  This has never happened to the other versions kernels and with the kernel in default Debian. Now i boot with kernel version 3.16, and with the same version of the driver wl, everything works as before. Every time compile source driver for the new kernel, i do not just copy the file wl.ko.

Comment 37 Lukas Wunner 2016-05-18 21:17:01 UTC
Thank you for the extensive testing.

I've looked at the b43 driver to see which steps I might be missing in b43_earlyquirk_4.4.patch and realized that before resetting the wireless core, it has to be mapped first. On my machine that step isn't needed but perhaps it is on yours.

Could you try the following: Apply the newly attached b43_print_core_addr.patch to a stock kernel, boot and load b43. The driver should now output the address and wrap for each core. Looks like this on my machine:
[ 3596.239935] bcma: bus0: Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x25, class 0x0, addr 0X18000000, wrap 0X18100000)
[ 3596.241657] bcma: bus0: Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x1D, class 0x0, addr 0X18001000, wrap 0X18101000)
[ 3596.243438] bcma: bus0: Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x13, class 0x0, addr 0X18002000, wrap 0X18102000)

Reboot with all wireless modules blacklisted (b43, bcma, wl). Invoke "lspci -vvvv -xxxx -s 03:00.0". You will get a hexdump of the wireless card's PCI config space. Look at the four bytes starting at positions 0x80 and 0xac. This is the address and wrap of the core that is currently mapped (in little endian order). For the patch to work, this needs to be the address and wrap of the IEEE 802.11 core.

E.g. on my machine, the four bytes at position 0x80 are 00 10 00 18 (= addr 0x18001000), at position 0xac it's 00 10 10 18 (= wrap 0x18101000).

Please let me know to which of the three cores the 2x four bytes in the config space correspond.

As for b43_eboot_4.4.patch causing the system to freeze when the broadcom-sta driver is used, I don't really have an idea yet what might be the cause. The high CPU load with b43 might be normal, I'll check this on my machine.

As for GPE 17, I can see that about 500 interrupts have accumulated for this GPE on my machine shortly after booting, something in the 20000+ range seems high indeed. After briefly looking at drivers/acpi/ec.c, I think it should be possible to determine what is causing the GPE to fire by adding some debug code to acpi_ec_query() so that the _Qxx number is printed. That number can then be compared to the _Qxx methods in DSDT. I'll see to it that I cook up a patch for that.

may be i introduce you astray. GPE17 actually has about 500 interrupts after boot (with b43_eboot_4.4.patch), 20000+ it after a long work laptop. if you have the same values after boot, i should calm down about this.
Comment 40 Lukas Wunner 2016-05-23 15:58:28 UTC
So the reason why b43_earlyquirk_4.4.patch doesn't work on your machine seems to be that the wireless card is in power state D3hot. I'm attaching a new version which transitions the card to D0 before resetting it. The commit message contains an explanation why the card is in D3hot. (It's caused by grub.)

Please let me know if this new patch works for you. I'd be glad to include a Tested-by: in the commit message so that you get credit for your testing efforts. If you would like to be credited with your real name, please send it to me by e-mail. If you prefer to remain anonymous, that is also fine of course.

As for GPE 17, I've hacked the EC interrupt handler to output the _Qxx number and the about 500 interrupts on boot seem to be caused by initializing the battery (_Q10). Afterwards I've only seen _Q40, which is related to the Ambient Light Sensor. This increases the interrupt count by 6 each time. Wave your hand in front of the camera (where the ALS is located) and the interrupt count on GPE 17 will go up fairly quickly.

works fine. after boot:

cat /proc/interrupts

17:    553          0          0          0   IO-APIC  17-fasteoi   mmc0, b43

Аlso is still proprietary driver wl makes the system to hang. If your patch is accepted into the linux kernel then it will be a surprise for those who use proprietary driver and once upgraded to patched version of the kernel.

It may be possible for Ambient Light Sensor disable send an interrupt? because it is not used for example for me, i always adjust the brightness manually.

Thank you very much for the detailed explanation and your patches.

I recompiled my kernel (4.5.4-1-ARCH) with your latest patch: >[PATCH] x86: Add early quirk to reset Apple AirPort card [+ resume from D3hot].

It seems to have fixed the IRQ problem on start up. I am run b43-firmware from AUR  normally but I have installed and configured as hr mentioned issues with that combination. 

I installed broadcom-wl from AUR, disabled b43 and ssb and modprobed wl. My connection doesn't seem as stable with this wl driver as with b43 but I haven't had the box hang on me or anything yet. 

hr do you have a good procedure to reproduce the freezing/hanging you are seeing with the wl driver? Could you provide more information about how and where it is hanging for you?'

Comment 45 Lukas Wunner 2016-05-26 19:32:25 UTC
Thank you Bryan. Is the dmesg output from when you tested it with wl? Because on that boot, b43 was used. Otherwise it looks fine, except for the Thunderbolt controller not being supported (which is fixed in 4.7) and the BIOS being from 2016 (which is odd, I thought the newest version was Apple's EFI Update 2015-002).

hr tells me that lockups only occur with large amounts of traffic. When transmitting just pings, things seem to work fine even over longer periods of time. Unfortunately I don't have a wifi AP at my disposal right now, I mostly use Gigabit Ethernet, so I have to lean on you guys to test it.

Comment 48 Lukas Wunner 2016-05-26 23:02:57 UTC
I've sent an e-mail to Broadcom support asking for help:
http://lists.infradead.org/pipermail/b43-dev/2016-May/003975.html

Michael Büsch (not at Broadcom but a regular b43 contributor) responded that my simplified reset procedure (which just sets the reset bit and does nothing else) might cause issues with wl and that I need to follow the procedure as per the bcma source code:
http://lists.infradead.org/pipermail/b43-dev/2016-May/003976.html

So I've just attached a new version of the patch which follows Michael's specification to the bit. Not sure if it helps but worth a try?

In the bcma source code we're actually doing a bit more, we're writing to the BCMA_IOCTL a couple of times. If the latest patch doesn't resolve the issue I could add that as well:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/bcma/core.c#n42
Comment 49 Bryan Paradis 2016-05-26 23:34:30 UTC
Hello Lukas, Dmesg was with b43 and now I have uploaded one with wl. Hadn't even thought to look into the Thunderbolt stuff yet. Just recently got this machine. Good to hear it's in 4.7!

As I am not familiar with the platform I have no idea about the EFI update version. My friend had updated the device to El Captain just before I received it. Packaged with it maybe? I have dumped the eeprom if you are interested. 

I have been doing internet based testing but my connection isn't very fast. I will setup some wifi/lan tests with high throughput. Will be interesting if I can reproduce the same issue hr is seeing or not. I was seeing lots of problems before but now it seems really stable now using: 

aur/broadcom-wl-dkms-248 6.30.223.248-1 [installed] (2) (0.03)

Interesting about the reset procedure. Nice of Michael to respond. Could make sense. Wonder if it will need he BCMA_IOCTL or not. Is there anyway to access the registers or any other information that might help when it is in an unstable state? If I can get it into one anyway. 

Takes a good while to compile on here (: I will get back to you a bit later with the results. Do you know which version of wl hr was using?

Thanks for info Bryan. I download last shapshot drivers https://aur.archlinux.org/packages/broadcom-wl-dkms/

Аnd find there something interesting, two patches:

001-null-pointer-fix.patch
002-rdtscl.patch

I applied them to the drivers who have installed so far:

https://www.broadcom.com/docs/linux_sta/hybrid-v35-nodebug-pcoem-6_30_223_271.tar.gz

And now have been no hangups everything works fine with patch Lukas.

Great, thanks for the research, it's good to know about that null pointer issue in wl and the corresponding patch. I've just sent the patch to the lists, let's see if there are any objections, bikeshedding requests, etc.

Comment 54 Bryan Paradis 2016-06-03 00:01:27 UTC
I was having some instability problems which I troubleshot down to some weird disassociation problems on the AP side. Updated my OpenWRT to 15.05.1 and dropped 40mhz width back to 20mhz. No problems since.

I haven't seen the errors in my dmesg as you hr.Could you provide any more context?
Comment 55 Bryan Paradis 2016-06-04 08:20:43 UTC
New information. I have been messing around with the kernel source see if I can get further towards a fix for this issue. Definitely something earlier in the UHS init is breaking the tuning. I am unsure. 

Can someone else confirm that me thinking that the BCM57785 has an on board voltage switching regular and so there is no reason that it wouldn't be capable of v1.8?

Unfortunately I just posted in the wrong bug. I don't think you will be able to glean any information about the current problem from that one. It was meant for https://bugzilla.kernel.org/show_bug.cgi?id=73241 but I got my windows mixed up.

As for an update here I have been running a kernel with the latest patch quite extensively for a few days with no occurrences of any wifi problems.

hr: I noticed that iwconfig and other wireless utilities need to be run as root to work else I errors like:

ERROR @wl_dev_intvar_get : error (-1)
ERROR @wl_cfg80211_get_tx_power : error (-1)

Could this have happened when using some sort of utility? Anymore information about it occurring?
Comment 58 Lukas Wunner 2016-06-10 10:57:08 UTC
Error -1 is -EPERM:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/include/uapi/asm-generic/errno-base.h

I can reproduce the error hr is getting by loading b43, unloading, then loading wl. Somehow wl is picky about the state the device is in and returns -EINVAL when scanning. But I believe this is independent from this patch.

By the way, the patch was queued by Ingo Molnar this week:
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=625a99d9bfd0

There was an objection raised post-merge which I've addressed, we'll have to see if there are others:

Thanks for posting that. Totally makes sense that this exists.
