Description htexmexh 2012-03-10 10:34:31 UTC

I get random xorg hangs where the only thing I can do is REISUB out. I am running the nouveau driver with xorg-server-1.9.5 and kernel 3.2.7.

I find this in /var/log/messages at the time of the crash:

I have gotten similar hangs with recent proprietary nvidia drivers, and that's why I switched to nouveau. I don't know if this is hardware related, but it didn't happen with older nvidia drivers.

Does this still happen with the latest kernel/mesa/xf86-video-nouveau? If so, please supply all the information requested at http://nouveau.freedesktop.org/wiki/Bugs/
