--- Comment #9 from Francisco Jerez <currojerez at riseup.net> ---
I've been trying to reproduce this failure on BDW today without success.  It
doesn't seem to make a difference for me whether I use X or GBM to run the test
case.

I noticed though that the DRM render ring code is missing a DC flush on
batchbuffer submission, what could lead to a non-deterministic failure in this
test case.  Can anyone try out the attached kernel patch and see if it helps? 
If it does this should be considered a DRM bug.
