I'm not sure if this is related, but I can still reproduce a GPU hang (which
results in no graphics acceleration and a lot of intel_do_flush_locked failed:
Input/Output error messages terminating programs) by running cairo-dock in
direct OpenGL mode (indirect works fine...).
However, a lot of

Looks like another mesa bug, if you have a clear set of reproduction
steps (as it looks like you do) I would open a fresh bug.

Just hit this bug again today, and see that I had not yet tried turning
on uxa. Doing so now to see if the problem recurs; however, the
reproducing interval is quite long so it'll be hard to tell if it's had
any effect.

Title:
[arrandale mesa] GPU lockup
I just had a GPU lockup again, and apport indicated it was a duplicate
of this one. The superficial symptoms were different; different error
message when trying to restart compiz, and unlike previously, the system
didn't go into an unresponsive high-load state. But that may have been

You mentioned this occurred after upgrading xserver-xorg-video-intel.
That may be coincidental, but if not (i.e. if downgrading to the
previous version makes the freezes stop), the first thing worth looking
at is switching back to UXA. To test that, put this in your xorg.conf:
