On a quick look this is a hange in the gen4 mesa code, nothing gone wrong
that could be blamed on the kernel part of the driver. Please upgrade to
the latest mesa (maybe even try git). If you can still reproduce this (and
you've figured out a way to reliably reproduce this), please file a bug
on bugs.freedesktop.org agains mesa -> intel/i965.

Thanks, Daniel
