Bug https://bugs.freedesktop.org/show_bug.cgi?id=107161 has mostly been fixed, aside from the following issue on SNB:

https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4602/shard-snb3/igt@kms_plane@pixel-format-pipe-a-planes.html

(kms_plane:2398) igt_debugfs-CRITICAL: Test assertion failure function igt_assert_crc_equal, file ../lib/igt_debugfs.c:371:
(kms_plane:2398) igt_debugfs-CRITICAL: Failed assertion: !mismatch
Subtest pixel-format-pipe-A-planes failed.
Comment 1 Matt Roper 2019-09-19 21:54:08 UTC
Failures from this test stopped happening about 11 months, 2 weeks ago.  I believe this upstream patch is what fixed the issue:
