--- Comment #66 from David Weinehall <david.weinehall at intel.com> ---
I compiled a new kernel using your latest wip-mutex tree (as of Tue, 03 Sep
2019 10:41:32 +0000).

The following tests were run (20 iterations each):

gstreamer_hd22_p50
ffmpeg_qsv_hd22_p50

both passed. We upped the number of parallel processes a bit; with 100
processes the tests still passed. With 150 processes the test failed due to out
of memory, but the failure was graceful--the machine recovered properly and no
panic, OOPS, or i915 GPU hang was triggered.

Once our nightly test finishes for the night I'll run one more test run with a
standard kernel (no lockdep, no KASAN).
