Thanks for testing. Don't worry about the retries, that's an integral part
of the new chipset flush. As long as it's a small number, everything's
fine (I've gotten higher numbers than you while testing).

The important thing is whether you still get backtraces about failed
chipset flushes (there's none in the dmesg you attached). iirc the
previous patch still had problems there for you.

If the BUG is causing you too much grieve while testing, undo the two
changes to drivers/gpu/drm/i915/i915_gem.c the patch makes. But that will
greatly reduce the number of chipset flushed, so massively hampering
testing. Otherwise just check you dmesg for any "chipset flush failed"
messages and hit the reset knob ;)
