Public bug reported:
Binary package hint: xserver-xorg-video-intel
Just experienced a hard lockup with my T60, no discernable cause.
The time frozen on the screen is 14:49, but the last log entries of
interest anywhere are some time before that.
/var/log/kern.log:

chvt hangs; xrandr hangs; glxinfo hangs (so I'm submitting this bug
report by hand, since ubuntu-bug can't collect any informaton without me
rebooting first)
This is the only time I've encountered a freeze of this nature so far.
I have the previous version of mesa loaded by the X server, not having
restarted it since the upgrade to 7.4-0ubuntu3; but since this is a 945
rather than a 965, I can't see why that would matter.
I don't run compiz, I haven't played any videos today, and TTBOMK I
haven't even been loading any different web pages than usual. My recent
activity was all in gnome-terminals. So I can't offer much as far as
hints for reproducing this.
I do have one setting of interest in my xorg.conf, which Bryce had asked
me to test:
Section "Device"
Identifier "Configured Video Device"
Option "ExaOptimizeMigration" "off"
EndSection
the xorg.conf is otherwise vanilla, aside from a Virtual setting. will
attach the full xorg.conf and intel_reg_dump output shortly.
