There are multiple lockups like this regarding I830WaitLpRing() in the
upstream bugzilla. The url above might be the most similar one, so I am
marking this bug as forwarded there.
Could you send the output of
/usr/share/bug/xserver-xorg/script 3>&1
so that we see your whole config and log?
If you have Option PageFlip enabled in your xorg.conf, you might want to
remove it since the upstream bug says it is related. If you have
xserver-xorg-video-intel 2:2.0.0-1 (the one in testing), could you try
with xserver-xorg-video-intel 2:2.1.0-1 (the one in unstable) ?
Do you have an idea when this bug started to occur? When upgrading
xserver-xorg-video-intel?
Once I'll have more info from you, I'll add a comment in the upstream bug.
