R9285 Tonga, probably since
36626ff radeonsi: split si_emit_shader_pointer
Xonotic big-key-bench timedemo may provoke a display/gpu lockup.
On head it seemed easy to provoke: one,two or three runs.
Bisecting was harder as it took more hence the possibility that I am on a false
good.
Currently on commit before above and haven't locked so far, don't know if
that's luck yet.
Lock seems to be same(ish) place in demo = frame 6512, though once it was 6514.
Waiting before doing SysRq I will get a timeout trace as below. I tried on
older kernels with same result, the dirty here is just a CPU fix I need that's
in rc-5.
