Description Tomi Sarvela 2018-07-09 07:51:06 UTC

Intel-GFX-CI is finding a lot of CRC mismatches after one wide filter was made more specific to its case. This issue can be seen on hosts from gen SKL forwards (SKL, KBL, APL, CFL, GLK)

and is found with tests

This seems to have been fixed, except for some SNB issues which have been filed here: https://bugs.freedesktop.org/show_bug.cgi?id=107932

Comment 2 Lakshmi 2018-10-13 14:06:49 UTC

This issue used to occur in every round IGT/CI_DRM/drm-tip.
Not seen since 1 month 4 weeks. Closing this bug.
