Description Francisco Cribari 2017-09-25 19:56:30 UTC
Created attachment 258599 [details]
Hardware description

I run Manjaro KDE (which is Arch-based). My notebook has an Intel 8260 wifi/bluetooth chipset. After linux-firmware was upgraded to version linux-firmware 20170907.a61ac5c-1 I started experiencing bluetoth radom disconnects and bluetooth crashes with kernel 4.13.x and 4.14 RC1 (but not with the LTS kernel, 4.9.51). The hardware description is the attached file. 

*

My full journal (the output of journalctl --boot) can be found at 

https://pastebin.com/2DJM1zKn

and output journalctl --boot | grep -i blue is available at 

https://pastebin.com/4MtxVeEz

I reverted back to linux-firmware version 20170622.7d2c913-1 and the bluetooth crashes stopped. I thus believe there may be a bug in the latest linux-firmware.
Comment 1 G Jaya Praveen 2017-09-27 07:09:01 UTC
Hi,

Can you please share the scenario, where you see the issue?

And also, FW you have got from Linux-firmware?
This is the last fw in the Linux firmware tree:
2017-03-07 linux-firmware: Update firmware patch for Intel Bluetooth,8260 

But from your description, i see a different version.

Can you please give the output of the fw version:
$sudo hcitool cmd 3f 05

Thanks.

Hi. With the previous (Arch) version of linux-firmware (20170622.7d2c913-1) I experience no bluetooth crashes. With the current version (20170907.a61ac5c-1) and recent kernels, however, bluetooth crashes after I use a bluetooth mouse for a while. After the crash I see 

[cribari@darwin5 ~]$ sudo systemctl status bluetooth

Comment 4 G Jaya Praveen 2017-09-27 10:41:35 UTC
Hi,

Can you please share the complete dmesg log and syslogs (/var/logs/syslogs).
From this log, it looks to be wifi issue, don't see any Bluetooth related issue.

Thanks.
Comment 5 G Jaya Praveen 2017-09-27 11:36:36 UTC
Also one more thing, can you disable wifi and just use Bluetooth and connect with the BT mouse and check if you still the issue.
Please check and update your results along with the logs (dmesg and syslog) for the failure case.
Comment 6 Francisco Cribari 2017-09-27 13:29:09 UTC
Hi. Here is the information you requested: 

https://pastebin.com/e4QjwbUk

Could the problem be related to this one? 

https://www.spinics.net/lists/linux-wireless/msg166025.html

I will try to disable wifi and use bluetooth and I'll report back on that.
Comment 7 Francisco Cribari 2017-09-27 13:43:48 UTC
Disabling wifi I was able to use a bluetooth mouse without crashes. The dmesg info for this case is available at 

https://pastebin.com/eQ1MTmGF

BTW, as soon as I turned wifi on my bluetooth mouse stopped working. At that point: 

[cribari@darwin5 ~]$ sudo systemctl status bluetooth

Interestingly, I do not experience any crashes when: (i) I use the latest firmware (20170907.a61ac5c-1) together with the LTS kernel (4.9.X), (ii) I use the previous firmware (20170622.7d2c913-1) with the most recent kernels (4.13.X and 4.14 RC1). The crashes take place when I use the latest firmware together with the latest kernels.
Comment 8 Emmanuel Grumbach 2017-09-27 14:47:37 UTC
Hi,

We will provide a debug firmware to collect debug data from the WiFi side.
How easily can you reproduce this:

[   88.796807] iwlwifi 0000:01:00.0: Microcode SW error detected.  Restarting 0x2000000.
[   88.796968] iwlwifi 0000:01:00.0: Start IWL Error Log Dump:
[   88.796976] iwlwifi 0000:01:00.0: Status: 0x00000200, count: 6
[   88.796982] iwlwifi 0000:01:00.0: Loaded firmware version: 31.532993.0
[   88.796989] iwlwifi 0000:01:00.0: 0x00000084 | NMI_INTERRUPT_UNKNOWN  


?

This means that the WiFi transmit queues are stuck and it is a good trigger point to collect the debug logs. The question is whether you see this a lot or not.
Do you have this anytime you can't work with BT, or?
Comment 9 Francisco Cribari 2017-09-27 14:59:07 UTC
Hi. I haven't looked at many dmesg dumps, but I've faced many crashes lately. I thus imagine that it is reproducible. If you give me a new firmware and instructions on how to install/use it (and collect the necessary data), I'll be glad to give it a try. A couple of comments: 1) I run Manjaro Linux and I initially reported the problem in their forum: 

https://forum.manjaro.org/t/bluetooth-crashes-since-updated-to-kernel-4-13-2/31809

2) I disabled bluetooth coexistence (bt_coex_active=0) about an hour ago (and rebooted) and since then I have not experienced any crashes.
Comment 10 Jacob C 2017-09-27 16:06:38 UTC
I can confirm that I'm also having the same issue as Francisco above, also on Manjaro.

My hardware is slightly different, Intel Corporation Wireless 8265.

8260 firmware with debug enabled

Hi,

Here is the firmware for 8260. Please copy it to /lib/firmware (I assume your distro takes it from there), you can backup the existing one before you overriding it.

The instructions on how to collect the data are here:
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging#firmware_debugging

Please take the time to read the privacy notice:
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging#privacy_aspects

Note that I reduced the timeout to 700ms to collect the data closer to the issue.

Of course, please re-enable bt coex.

With the results, I'll need to involve the WiFi firmware team. This can take time.

Thank you.

Does that help?
Comment 14 Emmanuel Grumbach 2017-09-28 04:06:18 UTC
Hmm.. That will probably help (will need to forward this to the firmware team), but this is not the same problem: you know hit this:

[ 3263.040021] iwlwifi 0000:01:00.0: Loaded firmware version: 31.560484.0

Comment 15 Emmanuel Grumbach 2017-09-28 05:04:03 UTC
I looked at the 2 dumps that you had in Dropbox.
One of them has been created manually it seems and I'll need your explanation on what happened when you create it (no BT, no WiFi, etc...). The firmware didn't crash by itself in that dump.
Along with that, I can seee a dump for the ASSERT 370C which is good.
Note that ASSERT 307C has nothing to do with BT, and therefore, I'll ask you to open a new bug, paste the dmesg output and the link to the dump in that new bug.
Please CC linuxwifi@intel.com on that new bug.

Thank you.
Comment 16 Francisco Cribari 2017-09-28 10:42:10 UTC
Hi. Thank you. I filed an new bug report: 

https://bugzilla.kernel.org/show_bug.cgi?id=197061

The dump files were created by the udev rule that I created following the instructions available at 

https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging#firmware_debugging

I don't recall what happened with the first one. I may have forgotten to issue 

echo 1 > /sys/kernel/debug/iwlwifi/0000\:0X\:00.0/iwlmvm/fw_dbg_collect

I decided to make both files available because there could be valuable information in the first dump file. 

I am dutifully reporting a bug I am facing. I hope the information I am providing proves to be useful for locating the problem and fixing it.

Yup - saw that. Thanks.

You shouldn't issue that command since you have a firmware crash and that collects automatically the data. No need to ask the driver to collect the data manually.

Data was sent to the firmware team for analysis.

Hi,

here is a fix candidate from the firmware team.

Please test.

Thanks!

I noticed the dmesg error messages below (Intel 8260 w/ BT coexistence off). Could they be related to the current bug?

Comment 21 Francisco Cribari 2017-11-21 01:15:34 UTC
More on the above errors: Firmware used is iwlwifi-8000C-31.ucode (from linux-firmware version 20171009.bf04291-1, Arch package). I do not have a dump file since I was not running a customized debugging firmware.
Comment 22 Emmanuel Grumbach 2017-11-21 22:17:40 UTC
Yes, this is a TFD queue hang.
Comment 23 Emmanuel Grumbach 2017-11-27 13:02:59 UTC
Created attachment 260897 [details]
New BT firmware

Here is a pre-release of the new firmware for BT.
Please copy the files to /lib/firmware/intel/

You'll need a hard power off / on cycle.

After boot,  run btmon in 1 terminal and in the other terminal give the command hcitool cmd 3f 05 in root permission.
After giving the hcitool cmd 3f 05 the btmon log will show the version information.

Please provide the btmon log.

Let us know if things feel better.

Note: this includes BT firmware for 8260 and 8265.
Comment 24 Francisco Cribari 2017-11-27 15:59:06 UTC
@Emmanuel Grumbach Here is the btmon log (Intel 8260 with BT coex on): 

https://pastebin.com/cCfBDLms

Does it help?
Comment 25 Emmanuel Grumbach 2017-11-27 16:09:49 UTC
Need to ask the BT guys.

Do you still have the wifi crash with this BT firmware?
Comment 26 Francisco Cribari 2017-11-27 18:58:16 UTC
@Emmanuel Grumbach No crashes so far (Intel 8260 com BT coex on and the new BT firmware).
Comment 27 Emmanuel Grumbach 2017-11-27 19:29:47 UTC
great - how often could you repro the crash before?
Comment 28 Francisco Cribari 2017-11-27 22:14:14 UTC
@Emmanuel Grumbach I have been using the testing firmware (w/ BT coex on) for about 8 hours and so far no crashes. Before crashes would take place in a couple of hours. So far so good.
Comment 29 Francisco Cribari 2017-11-27 23:18:55 UTC
@Emmanuel Grumbach My computer has experienced a crash. I don't know whether it was BT-related. The dump info is available at 

https://www.dropbox.com/s/g224p9srtar6rgo/btmon-2.out.gz?dl=0
Comment 30 Emmanuel Grumbach 2017-11-28 03:21:30 UTC
Please attach dmesg as well.
Comment 31 Francisco Cribari 2017-11-28 10:21:41 UTC
@Emmanuel Grumbach dmesg info available at https://pastebin.com/u8PTMhi8 .

can't see any 'crash' here.

Comment 34 Emmanuel Grumbach 2017-11-29 10:42:04 UTC
That's sad.

Happens only with BT?

What is the repro rate?

I'll need to send a wifi firmware with debug enabled.

Comment 36 Emmanuel Grumbach 2017-11-29 10:45:55 UTC
yeah ok.

So, please go back to the regular WiFi firmware.
Comment 37 Francisco Cribari 2017-11-29 10:54:55 UTC
I reverted back to the regular wifi firmware (iwlwifi-8000C-31.ucode) and rebooted (BT coex on). This is from dmesg:

I reverted all firmware changes (sudo pacman -S linux-firmware) and the errors remained. However, they do not show up when I disable BT coexistence. With BT coex off what I see in dmesg is:

Hi,

please record a firmware dump with this firmware.

Thank you.

Same instructions as in Comment 11 and same note about privacy.

Thank you.
Comment 41 Francisco Cribari 2017-12-03 15:22:38 UTC
@Emmanuel Grumbach Here it is. 1) dmesg dump is available at 

https://pastebin.com/quFBVZak

2) Firmware dump (Intel 8260, BT coex on) is available at

https://www.dropbox.com/s/sn2bi6bakii4rc0/iwl-fw-error_2017-12-03_12-16-17.dump?dl=0

The kernel I was using during the FW crash: 

[cribari@darwin5 ~]$ uname -a

Sorry, but I need a bit more data.
I reduced the timeout in the firmware attached.
Please keep tracing running and when the problem reproduces, please stop the tracing.

Thanks.
Comment 43 Francisco Cribari 2017-12-03 18:33:58 UTC
Emmanuel Grumbach You write: "when the problem reproduces, please stop the tracing." How do I stop the tracing? The dump file is being created by the udev rule.
Comment 44 Emmanuel Grumbach 2017-12-03 18:36:34 UTC
Ok, I wasn't precise enough.

I meant this:
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging#tracing


This is a user space process that records all the driver interactions. When the firmware crashes, you can just stop this user space process by hitting CTRL+C.
After CTRL+C, it'll collect all the data in one file (can take a few seconds), and then you'll have a trace.data file. You can compress this file and attach it here / dropbox / whatever.

Thanks!
Comment 45 Emmanuel Grumbach 2017-12-04 06:41:29 UTC
If you can, it'll be nice to check what happens with -34.ucode.
-31.ucode will be EOL'ed very soon and maybe we should just jump to -34.ucode for the debugging.

In order to make -34.ucode, you'll need to jump to 4.14.3.

Thank you.
Comment 46 Francisco Cribari 2017-12-04 10:19:49 UTC
@Emmanuel Grumbach 1) I am running the latest testing firmware (comment 44) but so far a crash hasn't happened, 2) I am running kernel 4.14.3, but I don't have firmware 34. This is what I have in /lib/firmware: 

[cribari@darwin5 firmware]$ ls *8000C*.ucode
iwlwifi-8000C-13.ucode  iwlwifi-8000C-21.ucode  iwlwifi-8000C-27.ucode
iwlwifi-8000C-16.ucode  iwlwifi-8000C-22.ucode  iwlwifi-8000C-31.ucode

The version of linux-firmware available in the Manjaro repositories is 20171009.bf04291-1. This is what I have installed on my system.

@Emmanuel Grumbach A crash has just taken place (firmware -31.ucode, BT coex on, kernel 4.14.3). The dmesg dump is available at 

https://pastebin.com/hS3c9sLt

The firmware dump is available at 

https://www.dropbox.com/s/m2xwpm4aill3id5/iwl-fw-error_2017-12-04_07-45-32.dump?dl=0

The trace data is available at 

https://www.dropbox.com/s/378qi2jesk4evlu/trace.dat?dl=0

(This last file is quite large! Please, let me know when I can delete it from my Dropbox.). P.S. I downloaded the -34.ucode firmware using the link in Comment 47 file but I noticed that it is much larger than the other files (16 MB). Is that correct?
Comment 49 Emmanuel Grumbach 2017-12-04 11:25:16 UTC
16MB is way too big :)

You should download this link: https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-8000C-34.ucode

I was sending you to a webpage :)

Just FYI, both the trace of the dump file compress very well. You can use any compression you like, they'll shrink considerably.
I have downloaded them.

With the -34.ucode firmware I had this in dmesg:

Hm... So BT problems again...
Comment 52 Emmanuel Grumbach 2017-12-11 19:42:57 UTC
Hi,

I analyzed the data and forwarded it to the firmware team.
I did find something, this seems to be related to changes in the power definitions.

I can see that you tried to set the power save with iw exactly one second before the crash which matches exactly with the timeout I set in this debug firmware.
At some point, our firmware gets confused.
Comment 53 Francisco Cribari 2017-12-11 20:19:23 UTC
@Emmanuel Grumbach You write: "I can see that you tried to set the power save with iw exactly one second before the crash". I made no changes to my settings, including to power saving. I can assure you that. I just booted the machine and used it as I normally do until the crash happened.
Comment 54 Emmanuel Grumbach 2017-12-11 20:32:56 UTC
 iw-901   [002] 16093.362208: rdev_set_power_mgmt:  phy0, netdev:wlp1s0(3), enabled, timeout: -1 


So someone invoked iw... Very strange.

Doesn't matter, this can be a hint on how to reproduce the bug faster.
I wrapped up all the data for the firmware team to analyze. I'll keep you posted.
Comment 55 Francisco Cribari 2017-12-11 20:36:15 UTC
@Emmanuel Grumbach You write: "So someone invoked iw... Very strange." Indeed. The machine is a notebook (laptop) and I am the only user (besides root). If that happened, it wasn't by my intent. Perhaps Manjaro or KDE Plasma did something on their own...
Comment 56 Emmanuel Grumbach 2017-12-11 20:38:22 UTC
Might be.
Maybe they track the ACPI event of plug unplug the power cord.
It is not a very good idea because the NetworkManager wants to control this as well, but it doesn't matter at this stage.
Comment 57 Emmanuel Grumbach 2017-12-27 11:29:16 UTC
Hi Florian,

I am sending a newer firmware to you via email.

Please use it with our backport based driver or with kernel 4.15.
Our backport tree is here:

https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git/


The firmware team has made significant changes in this area and would like to know whether you still see the bug on that newer firmware.

Thank you.
Comment 58 Emmanuel Grumbach 2017-12-27 15:07:13 UTC
Sorry, I got confused, I meant:

Hi Francisco :)
Comment 59 Francisco Cribari 2017-12-27 21:50:23 UTC
@Emmanuel Grumbach Due to some other errors I was getting, I am no longer running Manjaro Linux on that laptop. It now runs Arch Linux. Manjaro is based on Arch, but they are not not identical. Since I migrated to Arch I haven't seen any assert errors in the logs. I've used the machine with and without BT coex, and with the both stock Arch kernel and the zen kernel. So far, no assert errors.
Comment 60 Emmanuel Grumbach 2017-12-28 06:23:57 UTC
All right. Closing the bug then.
