dri_debug.tgz (after the second freeze the machine froze a third time right after I restored my firefox session)
To my untrained eye the freeze dumps I've posted in this bug looks somewhat similar to the GPU freeze I in the end of August (also using karmic):
One additional thing; when the machine froze the third time (just 1-2 minutes after rebooting from the second freeze) I had just restored my GNOME session which started gedit and a gnome-terminal and it also re-launched my Firefox session with around 10 TABs in one window. One of the TABs in Firefox had a 6507x1787 pixel PNG in it (I guess that's not huge but it's bigger than the average texture maybe?).
Does the patch in http://bugs.freedesktop.org/show_bug.cgi?id=22336#c18 help?

i965: Fix relocation delta for WM surfaces.
Please retest with this patch in Mesa, as it fixed issues when the aperture was near full (big images being a cause)
Ubuntu karmic cherry picked that "Fix relocation delta for WM surfaces" patch a few days ago so it's getting some nice testing right now before the upcoming Ubuntu beta.
I've been running with compiz off for the last few days (because I was previously getting _very_ frequent crashes while frequently generating and viewing huge PNG file for a project I'm working on).
Right now I've been running with compiz on, plus the patch applied and so far things looks great. No crashes or hangs and I've generated several big graphs, opened them in Firefox and Chrome, tried to stress it a bit with the compiz ring switcher and a few different games. So far, it feels pretty solid to me.
I'll report it here if the GPU hangs again with the patch applied.
OK, I'll go ahead and close it as fixed for now. Feel free to reopen if you see the same problem again. Thanks for testing!
