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
