≈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.</pre>
