Hi

My Xorg server on rawhide machine is giving me sudden X lockups with 3.1 kernel.
There might be couple issue related together as rawhide is now using
some experimental
Xorg server - but the message from kernel is a bit scary - so
reposting to lkml as well.

xorg-x11-server-Xorg-1.11.99.1-6.20111109.fc17.x86_64
git intel driver: 3b9479dc39d32fd97f80c1e5e0fac67d36ee5e40
drm version (a bit older): 8d055890d90c3d92647e3d8b98d32630ef87c2c8
(since current Fedora rawhide intel driver is so much broken it
doesn't even start)

Running desktop with only a plain  twm (no gnome-shell3 -  broken to
unusability as well).

Happened with just some mouse movement.
Might be related to https://bugzilla.redhat.com/show_bug.cgi?id=753703

My HW: Lenovo T61, gma965, 4GB, x86_64
