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.
Failures from this test stopped happening about 11 months, 2 weeks ago. I believe this upstream patch is what fixed the issue: commit 8e7a4424b996ab780b4cb4a4564f31e079e55711 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Thu Oct 4 15:15:27 2018 +0300 drm/i915: Fix ILK-IVB sprite enable delays
