Looks like you attached this already.

Please test the 3.4.y kernel from experimental. If it reproduces the
bug, please file this upstream following instructions from [1] and let
us know the bug number so we can track it. If it doesn't reproduce
the bug, we can try to find what upstream change fixed the bug.

Output from "reportbug --template xserver-xorg-video-intel" (as an
attachment) would also be interesting.

Sorry for the slow response, and hope that helps.

Sincerely,
Jonathan

I've been running the 3.4.4-1~experimental.1 for more than a week
without problems and when linux-image-3.2.0-3-amd64 (3.2.21-3) came out,
I reverted to that one and so far (after another week), no GPU lock ups
anymore.

So, without looking at the detailed kernel logs, I think the problem
simply disappeared (or was fixed by another Wheezy upgrade during that
time).

So, all is good right now, sorry for the noise, feel free to close this bug.

Cheers

Carsten
