Created attachment 89720 [details] [review] better-multithreaded-protection-for-cence-channel After almost 2 weeks running with this patch - the same problem happen. Looking bit more on nouveau_fence_wait function looks like I miss one place where multithreaded problem could occur - hence second patch to for it. *** Bug 72599 has been marked as a duplicate of this bug. *** Created attachment 96364 [details]
stacktrace from kernel oops
same here (with a slightly different stack trace), see attachment
(using 10de:06e4 (GeForce 8400 GS Rev. 2)).
Was simply using fluxbox/firefox after a resumed. It's the first time it happens, (but I changed a couple of kernel options only 2 days ago).
I will attach the .config diff in case there's something related.
Will try the patch later if I can get the oops frequently enough.

.config diff
seems that it never happened with my previous config (used during several weeks), but happened (once) with the new one (used only 2 days)
[ anyway other software was updated too in the interval ... ]
Looks like I've run into the same problem. X crashed while I was using Firefox and I found the traceback below in my logs. There were no errors in the Xorg logs so I've omitted those. I'm running Debian 7.5 amd64, kernel 3.13.5, Xorg 7.7, Nouveau 1.0.10-1+b1. Graphics card is a GF114 [GeForce GTX 560 Ti] (rev a1).
