kern.log (GPU lockup in the end)

GPU lockup happens while playing game (WarThunder), making the whole system
unresponsive for some time. The bug happens in one specific condition - when
firing guns in game (it also causes some mesa errors). It does not depend
whether game is played under wine with OpenGL render or linux version. 


Testing of linux version is currently blocked by bug
