Created attachment 57816 [details] Debug info generated by Debian tool Since I moved to Gnome 3, I experience a freeze of the nouveau driver. I never experienced a freeze with Gnome 2 or XFCE. Under a normal use the freeze happens once a week or so, but I have been able to reproduce it almost deterministically: - launch Gnome Shell - open my RSS reader (Emacs/Gnus) - quickly open several RSS items, which creates several tabs in Firefox (in particular this triggers the notification pop-up at the bottom of the screen) The freeze inevitably occurs then. Display entirely frozen except the mouse. I am able to SSH into the machine, kill the X server and start a new one. But the display remains frozen, so reboot is the only way to restore a sane state (I could not unload the "nouveau" kernel module). I am using Debian testing ("Wheezy"), which has version 0.0.16+git20111201+b5534a1 of the nouveau driver. I attach some debug output created using Debian debug script, a full kernel log, and a GDB trace that I generated by attaching to the X process while it was in a frozen state. Don't hesitate to ask for more debug information, since I have a way to reproduce the problem.

Please retest this with more current software and see if the problem still happens. (For the purpose of this discussion, "more current" means kernel >= 3.10, mesa >= 9.1, xf86-video-nouveau >= 1.0.9)
I no longer have access to the hardware. I am therefore closing this issue.
