Can you bisect which commit broke it?

Considering Marek's strong request on 12.0.6 can we bisect this please ? It should require up-to 5-6 steps (using -- src/gallium).
As usual -> please give 12.0.5 a try first.
12.0.4 is working fine* on r600 (turks). Looks like SI compute problem. *fine: within limits of what I know was broken in LLVM 3.8
Not reproducible on Hawaii.
Igor, can you test 12.0.6?
Support for mesa 12.0 ended long ago and the bug reports the issue was gone in 13.0 so marking as wont fix.
