--- Comment #2 from Thomas v10lator@myway.de --- Alex Deucher: Any news on this? Currently I'm experiencing GPU stalls under heavy load (gaming, so far tested with Left 4 Dead 2 and Distance, both games need around 15 minutes of gameplay before screen freezes) and while I would love to debug this I can't as I'm pinned on the patched kernel (4.0.4) so I can't even test if a newer kernel would fix the issue (which came with a mesa update).
