Please send the whole output of
   /usr/share/bug/xserver-xorg/script 3>&1
so that we see your full config and log (reportbug would have done that 
for you automatically).

If you could do that after the crash occured, that would be very nice 
(by logging from ssh for instance). If you can't do that, have a look at 
/var/log/Xorg.0.log.old after the next restart of the X server, it 
should contain the log of the previously crashed session. Send it to us.

The bug is probably in xserver-xorg-video-intel, I guess you're using 
2.2.0, we'll see in your reply.
