Xorg log with crash

About once every couple of weeks, my display locks up. Sometimes I am able to switch virtual terminals and reboot; sometimes after switching virtual terminals, something tries to restart X and the display becomes completely garbled and unusable. I can't reproduce this reliably, but it generally seems to happen when I have a lot of windows open and am in the middle of doing something like opening a new window or switching to the Gnome Shell overview.

I filed a bug with Debian a few months ago, haven't heard anything: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=744166. Here are a few lines excerpted from dmesg that seem to indicate when the problem started on that crash (I forgot to save dmesg output from the most recent crash before rebooting); the rest is included in the Debian bug report (sadly, appears not to be complete; I'll increase my log buffer size and get a full log the next time this happens). I've attached my Xorg.0.log.old from my most recent crash, and the Xorg.log from the older crash is attached to the Debian bug report.

If there's any other relevant information I can provide, let me know. I can't reproduce this on demand, and I don't have a known good version to bisect from; I switched from Mandriva running the proprietary drivers (which seemed to have some problems of their own, causing substantial slowness), to Debian running nouveau, and the problem has been happening occasionally ever since the switch.

dmesg from most recent crash
Comment 3 Andrew 2014-11-13 14:10:35 UTC
I have the same issue (same symptoms and apparent cause). I can usually SSH into the box, however a hard reset is required before the GPU will function again. A soft reboot (using reboot or halt) leaves the screen on and with whatever image was there when he GPU locked up. Generally the lock up occurs when interacting with firefox but that might be coincidental.

Here is the tail end of dmesg last time it occurred:

Comment 4 Patryk Zawadzki 2015-10-05 11:28:31 UTC
I am getting a slightly different error and am not sure whether it's the same issue:

nouveau E[   PFIFO][0000:01:00.0] read fault at 0x0011980000 [PAGE_NOT_PRESENT] from PGRAPH/GPC0/PROP on channel 0x00bf739000 [Xorg[2305]]

After that the screen freezes and I need to do a hard reset. Applications continue running and I can SSH in but restarting Xorg and trying to soft reboot do not help.

Just got some more:
