A CI Bug Log filter associated to this bug has been updated:

{- BYT: some igt@kms_draw_crc@draw-method-* - fail - Failed assertion: !mismatch -}
{+ BYT BSW: some igt@kms_draw_crc@draw-method-* - fail - Failed assertion: !mismatch +}

New failures caught by the filter:

  * https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_265/fi-bsw-kefka/igt@kms_draw_crc@draw-method-rgb565-mmap-cpu-untiled.html

The test failure reported by this bug consistently happened on BYT platform more than 6 months ago, but no recent failures.

I see the test is no longer running on the BYT platform:
https://intel-gfx-ci.01.org/tree/drm-tip/fi-byt-clapper.html

This test is currently running only on the shard systems:
https://intel-gfx-ci.01.org/tree/drm-tip/igt@kms_draw_crc@draw-method-rgb565-mmap-gtt-untiled.html

I can no longer see the dmesg logs from the previous failures to confirm what assertion has failed, but it appears to me that this bug is reporting the CRC mismatch failures that have already been reported in other bugs.
