dmesg output after crash

The system randomly freezes. I can still move the mouse but can't do anything else. I cannot switch VT, the three-finger salute does not work and system shut down via ACPI does not work either. The only way of recovery is a hard switch off.

The crash seems to occur more frequently, if I play videos (mplayer or Flash), but this is not a requirement.

The crash does not occur, if I use the blob firmware (nouveau.config="NvGrUseFw=1").

Comment 4 Ilia Mirkin 2016-01-07 14:10:49 UTC
I doubt this is it, but this patch only made it into 4.1.13:

https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=930a50a45963c8da0a27fbee73ae462d8ea54aca

The manifestation of that bug was different though, so ... probably unrelated. Wouldn't hurt to update though.

There have also been slight updates to the ctxsw fw in kernel 4.4, so you could try 4.4-rc8 and see if the issues remain. (Also the driver got a substantial refactor/rewrite in kernel 4.3.)

Either way, please check on latest to see if issues persist.
Comment 5 Matthias Nagel 2016-01-07 14:22:06 UTC
I also reported bug #93630 at the same time. Both problems occur in turns. I do not know if they are related, because the symptoms are completely different, but they both disappear using the blob firmware.
Comment 6 Matthias Nagel 2016-01-07 14:28:29 UTC
OK, I will test kernel 4.1.13 and 4.3.3. Both are available in the unstable branch of my distro. I cannot test 4.4.x yet. Let's see what I will find out.
Comment 7 Matthias Nagel 2016-01-08 11:15:02 UTC
The error also occurs with kernel 4.1.13 and 4.3.3.

First time it happened while playing a H.264 video with mplayer, the second time while scrolling a LibreOffice document.

Same dmesg messages.
Comment 8 Matthias Nagel 2016-01-20 19:09:21 UTC
Today, I finally managed to give kernel 4.4.0 a try. When I try to use the proprietary firmware I get to following boot error

Jan 20 20:01:44 kernel: nouveau 0000:01:00.0: Direct firmware load for nvidia/gk106/fecs_inst.bin failed with error -2
Jan 20 20:01:44 kernel: nouveau 0000:01:00.0: gr: failed to load fecs_inst

Where do I get this firmware from? Until now (<4.4.0) I used the following kernel parameters

CONFIG_CMDLINE="nouveau.config=\"NvGrUseFw=1\""
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="nouveau/nve6_fuc409c nouveau/nve6_fuc409d nouveau/nve6_fuc41ac nouveau/nve6_fuc41ad"
CONFIG_EXTRA_FIRMWARE_DIR="firmware"

and used the firmware found in bug 72180 in attachment https://bugs.freedesktop.org/attachment.cgi?id=90180
Comment 9 Ilia Mirkin 2016-01-20 19:14:57 UTC
The driver's expectations of firmware were changed in

fuc409c -> fecs_inst
fuc409d -> fecs_data
fuc41ac -> gpccs_inst
fuc41ad -> gpccs_data

And it wants the files to live in nvidia/gk106/ (or whatever the relevant chip name).

Ben's belief is that everyone should be fine with nouveau firmware, and the fact that the nvidia firmware works at all with nouveau is a fluke.

Sorry, all of those should have .bin at the end (i.e. fecs_inst.bin, etc)
Comment 11 Matthias Nagel 2016-01-20 19:25:07 UTC
Ok. Let's restate it in my own words to make sure I understood you correctly.

But first, let me say that I already have tried 4.4.0 without proprietary firmware. To this end I omitted nouveau.config="NvGrUseFw=1". I experienced the same crash with freeze while scrolling a LibreOffice Writer document. So bad news the bug is still there.

Now, I wanted to check if 4.4.0 with proprietary firmware works without crashing. For this purpose you want me to rename

nouveau/fuc409c -> nvidia/fecs_inst
nouveau/fuc409d -> nvidia/fecs_data
nouveau/fuc41ac -> nvidia/gpccs_inst
nouveau/fuc41ad -> nvidia/gpccs_data

These are essentially the same files but with a different path and name. Then I change

CONFIG_CMDLINE="nouveau.config=\"NvGrUseFw=1\""
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="nvidia/fecs_inst nvidia/fecs_data nvidia/gpccs_inst nvidia/gpccs_data"
CONFIG_EXTRA_FIRMWARE_DIR="firmware"

After re-compilation I should have a new kernel that uses the proprietary fw and I should be able to check if the crash with freeze is still there or not.

and a gk106 in between nvidia and the name, i.e. something that matches the error message it's giving you:

Comment 14 Cedric Brandenbourger 2016-04-05 13:14:21 UTC
Hi i can confirm the problems with the GTX660 firmware.
I'm using Debian 9.0 Stretch with Kernel 4.4. When using the nouveau firmware i got random freezes. After installing the nvidia driver, the freezes disappeared.
I then found this bug report, an the solution with using the nvidia blob firmware is working like a charm

Comment 15 Alexandre Courbot 2016-04-06 02:38:35 UTC
I think I am facing this issue.

Kernel 4.4.5, Arch Linux, GeForce GTX 650 Ti Boost (first time using it).

X will freeze almost immediately (typically right after my KDE session has loaded) with the following message:

nouveau 0000:01:00.0: fifo: write fault at 00002a2000 engine 00 [GR] client 0f [GPC1/PROP_0] reason 02 [PTE] on channel 2 [023faf0000 Xorg[666]]
nouveau 0000:01:00.0: fifo: gr engine fault on channel 2, recovering...

If have just booted using the NVIDIA firmware (NvGrUseFW=1), and X is working fine so far. Will perform a few more boots and spend some time on it to confirm the issue is solved.

This seems to be a GR firmware issue, any guidance on how I can help fixing it?
Comment 16 Dan Moulding 2016-04-13 16:23:31 UTC
I'm experiencing this bug with kernel 4.4.6 and GK106 (GeForce GTX 645 OEM).

For what it's worth, I've been experiencing this same bug for about two years, ever since kernel 3.12 (I was on kernel 3.10 prior to that and never experienced the bug). After each kernel upgrade I've done, I usually test the built-in firmware to see if the problem is still there. For a while, I thought the bug was gone as of the 4.4 kernel because I hadn't experienced the problem for a long time on 4.4 with the built-in firmware. But recently I upgraded my desktop environment to KDE Plasma 5 and now I've experienced the lockup twice in less than a 24-hour period.

I just switched back to the proprietary firmware (after moving/renaming the binary blobs to match the names that the new version of the driver looks for).

I'm willing to test the built-in firmware more, in order to help debug this longstanding problem. Is there something I can do to help gather more information (traces, enable debug logging, etc)?

if you are _sure_ that it never happened with 3.10 it would be really good if you git bisect the kernel and see which commit broke it. If you wait like one or two days for a freeze you should be through in a month :/

But maybe there is somebody who might know what it could be if it is really new with 3.12 (or 3.11)
Comment 18 Alexandre Courbot 2016-04-27 09:22:28 UTC
Compiled and booted a 3.10 kernel in order to attempt a bisect, but the issue showed up on that version as well:

Using the external firmware, I cannot reproduce the problem on this kernel either. So it seems like the NVE6 firmware has a long-standing bug.

Race condition fix for nouveau firmware

For anyone who experiences random hangs using the nouveau firmware and have spotted "SCHED_ERROR [ CTXSW_TIMEOUT ]" in the logs, please build a kernel with the attached patch and run using the nouveau firmware. Minimum kernel required is 4.6.

I've tested this on one machine of my own and have a strong indication that this improves the situation, but unfortunately it is difficult to distinguish random infrequent hangs from no hangs.

Comment 24 Matthias Nagel 2016-05-13 14:13:15 UTC
I tried to test both patches on top of 4.6_rc7. I can't tell if this bug is repaired, because I immediately ran into bug #95054 and another new bug I haven't had so far within seconds after I logged into KDE.

After three attempts for each patch I gave up trying. Sorry, I am of no help in this case.
Comment 25 Alexandre Courbot 2016-05-13 14:15:27 UTC
Weird, I also started Plasma 5, successfully.
Comment 26 Dan Moulding 2016-05-13 16:10:27 UTC
I've been running a 4.4.8 kernel, so had to build a 4.6-rc7 kernel. And, to be sure, I also wanted to first verify that I can reproduce the problem on unpatched 4.6-rc7. It took about 6.5 hours before my system locked up on 4.6-rc7.

Now I'm going to apply the patch (the alternate one from Ben) and see how that goes.

Ben, the alternate fix did not work for me. I got the CTXSW_TIMEOUT after just under an hour with that fix applied to 4.6-rc7.

Well, dang. Roy's patch doesn't work for me either. I got CTXSW_TIMEOUT after only 22 minutes this time (4.6.0-rc7 + Roy's patch).
Comment 29 Alexandre Courbot 2016-05-16 08:51:54 UTC
Of course, I'm a f****ing idiot. I had "NvGrUseFW=1" dangling in /etc/modprobe.d, so I was using the external firmware during my trials. :/

Remove it, and similarly to Dan I can reproduce this error with both patchsets. Sorry. :(
Comment 30 Dāvis 2016-05-17 16:13:59 UTC
I think I'm getting this same bug with Nvidia GTX 650 Ti on Arch Linux using unpatched released kernel 4.6, xf86-video-nouveau 1.0.12 and mesa 11.2.2

Sometimes random hangs happen which locks up GPU.
Note that nouveau have never really worked for me on this PC with this GPU for like more than a year since I installed Linux there. It always have been getting random hangs like other bug #89912 So I've been using proprietary Nvidia driver which works fine.



Anyway for this bug, I'm using GNOME Shell and it happened while playing Minecraft (with java-8-openjdk)

and here GPU lockup, but kernel itself didn't hung and works fine,
using SSH I was able to kill Xorg, unbind VT and unload nouveau and then reload it again

# echo 0 > /sys/class/vtconsole/vtcon1/bind
# rmmod nouveau
# modprobe nouveau
# echo 1 > /sys/class/vtconsole/vtcon1/bind

then I started Xorg and it works, and in kernel log can see

Comment 31 Cedric Brandenbourger 2016-06-25 12:33:10 UTC
Just installed Kernel 4.6 and now i'm getting the following message:

kernel: nouveau 0000:01:00.0: Direct firmware load for nvidia/gk106/fecs_inst.bin failed with error -2
kernel: nouveau 0000:01:00.0: gr: failed to load fecs_inst

Does the directories have changed again?

I also tried the original nouveau firmware with kernel 4.6. I think it's more stable but when i'm watching a video, totem or vlc are at 100% of CPU

Needless to say, recovering does not help, X hangs completely.

If there is a work-in-progress kernel module, I will gladly test it for you, thanks
Comment 34 Martin Assarsson 2016-10-27 14:39:29 UTC
Some days this lockup occurs multiple times.
I can log in to the machine via ssh but UI is completely locked.
Have tried to forcefully kill gdm and restart it, and successfully got it running, but not for long.

Same issue, Ubuntu 17 with kernel 4.10.0.32.32

kernel.log shows:

Then the machine hangs (frozen, but can still move the cursor) and I have to power off. It's pretty regular at this point, so if more info is required let me know what and how to get it.
Comment 38 Robb Ebright 2017-09-02 06:16:06 UTC
I ran into a similar bug with a recent Debian install. It occurs only when I plugged in a monitor into the DVI port. It works fine with the HDMI port as I'm using it to type. But it freezes with the following error.

I'm installing the proprietary drivers so but I wanted to provide this confirmation/documentation in case it is helpful to anyone trying to solve this. In an ideal world I would use the free software drivers as well but there is evidently some issue with the software that is causing it to crash.

Comment 41 Pierre Moreau 2017-11-21 23:27:12 UTC
t-IX and Dustin, you are experiencing a different bug: the current bug report is about a context switching timing out on GK106/GK107 (Kepler architecture), whereas you are using different chipsets (GF106/GF108: Fermi architecture) and the log you provided do not mention the CTXSW_TIMEOUT error. Please open a separate bug report where you also describe what you were doing at the time of the crash/freeze.

Robb, you are most likely hitting a different issue as well, so please open a separate bug report, including the kernel version used and which GPU model you have (you can get it by running `lspci -d 10de:`).
Comment 42 Jan Vlug 2017-12-31 11:43:05 UTC

The easiest way to reproduce is to leave the computer alone for a while and more often than not, the KDE desktop will lock up. But it also locked while I was actively using it about 1/2 hour ago.

I used to be able to ssh in and type "init 4 ; init 5" and successfully restart KDE. Unfortunately, someone made SSH access tighter recently and I can no longer do that ("Connection refused").

Comment 46 Franco Forza 2018-12-08 22:02:27 UTC
I've tested the 'NvGrUseFw=1' kernel cmdline argument (as stated in old comments from 2016 above) but it doesn't help anymore (the 4 requested fw files by nouveau during early boot were served properly and the errors about missing firmware files vanished as well).

The system freezes maybe once per week. Mostly hard crash with two keyboard leds blinking and hard reset after some time. Sometimes the kernel survives and dmesg can be read out. It shows this:
[ 7896.354441] nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]

If there's something we can do to help debug this let me know.
