Hi. I just wanted to say that I was hitting this bug too. It seems to be
a problem associated with xscreensaver and/or OpenGL. Looking for
information on the web I found some bug report that said something about
OpenGL (I can't find it now) so I tried deactivating xscreensaver and
the system is working very stable, no GPU hungs in 10 days of uptime.
When I had xscreensaver active the X server crashed in a couple of days
and sometime I got the GPU hung error in dmesg but X didn't crashed.

Thanks.

This homeless guy asked me for some money the other day.
And I was gonna give it to him but then I thought you're
just gonna use it on drugs or alcohol.
And then I thought, that's what I'm gonna use it on.
Why am I judging this poor bastard.
