Does the problem also occur without DPM?

BTW, in case your Mesa is built with --enable-r600-llvm-compiler, does the
problem also occur if you disable the LLVM based shader compiler with the
environment variable R600_LLVM=3D0 for the SL process?

That's just not true, see comment #3=
. Also (to preempt another concern you
mentioned on IRC), bisecting normally doesn't require any knowledge of the
code.

Unfortunately, I'm not able to reproduce anything like what you describe wi=
th
that apitrace on my machines.


> I crashed my machine 5 times in order to record =
this.

Five iterations of git bisect would go a long way towards isolating the
problem. If you had started the bisection when you reported this bug, you w=
ould
have isolated the change introducing the problem for you a long time ago, e=
ven
if you only tested it once a day.
