=E2=89=88=C2=BD of lockups are leaving screen black, and require reboot.

Attaching vs,gs,ps assembly, and R600_TRACE results from 2 different lockup=
s.
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.

=E2=89=88=C2=BD of lockups are leaving screen black, and require reboot.

Attaching vs,gs,ps assembly, and R600_TRACE results from 2 different lockup=
s.
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.<=
