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.
