--- Comment #3 from nine@detonation.org --- I can confirm that http://cgit.freedesktop.org/mesa/mesa/commit/?id=6532eb17baff6e61b427f29e076... is the first Mesa commit where the lockups occur.
With http://cgit.freedesktop.org/mesa/mesa/commit/?id=24b1206ab2dcd506aaac3ef656a... it still works on kernel 3.8.0-rc4
Is there anything else I can do to help fixing this bug?
