This test always fails:

but, in addition, often screen goes black, and kernel spews a message about lockup:

≈½ of lockups are leaving screen black, and require reboot.
Attaching vs,gs,ps assembly, and R600_TRACE results from 2 different lockups. The 2 traces are identical except that 1-st one locks up at the start, and the other at the end.
I've tried fixing it myself, but I have no slightest idea what to look at.

--- Comment #3 from Hi-Angel Hi-Angel@yandex.ru --- Some more info: for hard lockup SysRq and network stops working. I managed to get a trace for hard lockup using netconsole before network disappeared. An interesting part may be "Wait for MC idle timedout !" — I never saw it before.
