Bug 429642 – =sys-kernel/gentoo-sources-3.5.0 with =x11-drivers/xf86-video-nouveau-0.0.16 - After enabling 3D acceleration X often crashes, segfaults on restart

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Luca Wehrstedt 2012-08-03 13:12:27 UTC]

I have a NVIDIA GeForce 8600GT graphics card. I've been using nouveau for more than a year by now without any kind of problems. Yet, a few days ago I enabled the last kernel options I needed to get 3D hardware acceleration. Since then I'm having some issues. Some times X suddenly hangs (I cannot even move the pointer) and, after a few seconds, it crashes and I see a TTY console. Then, I think, gdm tries to restart it and after a few seconds I have again some graphics on the screen which often is a corrupted image of what I was seeing before the crash. Then X crashes again, gdm tries to restart it and so on until I get to log in the TTY and kill gdm (and xdm).

I have been able to get the dmesg output in one of these situations and an X log. I'll attach them both to this bug. In the dmesg logs you'll see some "SysRq : Keyboard mode set to system default" messages. That was me trying to get a usable keyboard to log in the TTY, because I was getting some keys double-typed and other missed. The X log is from one of those X processes that gdm tried to start *after* the first crash.

I can't see a pattern in the situations that cause this to appear: for example one time I was opening the browser, another time I had just closed a video player. On the other hand the 3D acceleration works just fine: I've been able to play openarena with a high framerate.

I'm not able to reproduce this bug at will. Yet, it happens frequently, several times a day.

Reproducible: Sometimes

The X.org log

[Comment 3 Luca Wehrstedt 2012-08-05 09:23:32 UTC]

I think this problem may be related to a suspend/resume issue. Yesterday I worked all day without a single crash. Then I suspended the computer for the night and today, a few minutes after resuming it, it crashed. I cannot remember if this was also the case the other times this bug happened, but since I suspend frequently it's very likely.

I'm attaching again some logs from dmesg and X. This X log comes from the first crash, and not from subsequent ones.

This looks like a kernel problem. You could try using x11-base/nouveau-drm instead of in-kernel nouveau to see if it is fixed in newer nouveau code.

If not, it would be good to file a bug for this at https://bugs.freedesktop.org/ (if no report already exists) so that upstream is aware of the issue.

> 3.5.0-gentoo

Can you try more recent kernels like the stable gentoo-sources-3.6.11 or the development git-sources-3.8_rc3?

[Comment 8 Luca Wehrstedt 2013-01-20 18:03:37 UTC]

Sorry, I forgot to mention here that I fixed this issue after reporting it upstream: https://bugs.freedesktop.org/show_bug.cgi?id=54359
