           Summary: [CI][SKL+] kms_draw_crc, kms_flip,tiling,... -
                    igt_debugfs-DEBUG: CRC mismatch at index 0:

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
