--- Comment #25 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Situation seems to have improved during weekend.  I don't see anymore rest of
the tests after HdrBloom & Multithread failing, and even those 2 tests now
succeed (with lower FPS), although there are GPU hangs.  Hopefully that was
real improvement and not just random / luck.

> Given that this used to work in past kernels, would it be possible to bisect?

In comment 12, I bisected it to within a day, rest is up to kernel team.  At
least the test-case is simple, just running single program 20x times.

(My manager doesn't approve me spending time on debugging other teams bugs, but
when test-case is easily reproducible and and I have pre-built daily kernels
available like was the case here, I can bisect issues to a regressing day
without it taking too much time.)
