This might be two separate bugs, but since they share a common cause I join them in a single report. I am not sure either whether this is the correct package to report the bug against, please feel free to reassign it if I am wrong. Bug#1: This first time it happened, I was trying to display a 2200x1200 px png image using qiv, a few days ago. X crashed and I got back to gdm login. Today, I tried to display a 3000x3000 px jpg image[1] in Iceweasel. It first crashed as above. I got a backtrace in Xorg.log featuring calls to the nouveau driver, but cannot be more precise since I sadly lost the trace in subsequent crashes (see below) and have not been able to reproduce it since then. dmesg did not contain anything relevant about this crash (see /var/log/syslog below @ 12:41:31 - gdm error message). [1] http://geoeyemediaportal.s3.amazonaws.com/assets/images/gallery/ge1/hires/tehran_iran_02_11_10.jpg Bug #2: I tried to load again the above-mentioned image and got a kernel oops; a few seconds later, a second oops occurred and froze the machine. After a reboot, I have been able to reproduce the bug: - load the above image in Iceweasel, - while it is loading (it takes some time), move the Iceweasel window and resize it. [I am using Xmonad, so this basically boils down to open new terminal windows and change the layout.] - some parts of the image become dark, you see a kernel oops in your terminal window, the image continues to load slowly, the second oops happens and then the screen becomes black. It always takes two oops to freeze. Since I have a way to reproduce the bug, I can try to get more information if you tell me precisely what you expect (I have no experience of any kind with kernel/X debugging). See the attached files syslog-2.6.32 (look for "Oops") and Xorg.log (nothing relevant I fear).

Yes. See the attached file syslog-2.6.34. Note that this bug is very similar to a bug reported on the dri-devel ML: http://www.mail-archive.com/dri-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org/msg46220.html But this bug has been corrected: http://www.mail-archive.com/dri-devel-5NWGOfrQmneRv+LV9MX5uipxlwaOVQ5f@public.gmane.org/msg47752.html And the fix is included in linux-2.6_2.6.34-1~experimental where I can still reproduce the problem, so this is likely a different issue (although similar).
