Comment # 10 on bug 91865 from Dieter Nützel

OK, 

is this SOLVED by 'accident'?

For RV730 GPU hang (Bug 83319) the above identified commit do NOT solve the
hang.
(Bug is updated, now.)

The observed issues with R600_DEBUG=nosb for all three 'raytrace' variants
(vsraytrace/fsraytrace/gsraytrace) stays.
latest: Mesa 11.2.0-devel (git-6470435)

I'll open a new ticket for this.
