Priority: medium Bug ID: 81072 Assignee: nouveau@lists.freedesktop.org Summary: GPU lockup after "read fault at 0x0000039000 [PAGE_NOT_PRESENT]" QA Contact: xorg-t...@lists.x.org Severity: normal Classification: Unclassified OS: Linux (All) Reporter: brian.campb...@editshare.com Hardware: Other Status: NEW Version: 7.7 (2011) Component: Driver/nouveau Product: xorg Created attachment 102454 --> https://bugs.freedesktop.org/attachment.cgi?id=102454&action=edit 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.

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. -- You are receiving this mail because: You are the assignee for the bug.
