Hi,
I've reported a few hangs/crashes since Jaunty alphas, but thought they had
gone away, I hit another one last night and have some debug - it happened as I
closed a tab in firefox (the button was still highlighted inwards) - the mouse
cursor continued moving but nothing else worked (not even capslock) - it's not
repeatable; my machine has an i945GM with an internal LCD and an external
monitor. This was running a 2.6.28-12 #42 from Daniel Chen with a sound fix.
Gdb attach to the Xserver gives:
(gdb) where

I killed off the Xserver and it didn't restart - the following was in
the logs:
[57243.381583] [drm:i915_getparam] *ERROR* Unknown parameter 6

Those unknown parameter 6's seem to happen pretty regularly but don't seem to
cause any issues.
Machine doesn't run compiz.
(My earlier Jaunty issues were in #346910 - although I haven't had any
crashes to blue like that recently).
