During a pre-merge run, the test igt@kms_frontbuffer_tracking@basic failed on fi-bdw-gvtdvm with the following error: (kms_frontbuffer_tracking:3702) igt-debugfs-CRITICAL: Test assertion failure function igt_assert_crc_equal, file igt_debugfs.c:325: (kms_frontbuffer_tracking:3702) igt-debugfs-CRITICAL: Failed assertion: !mismatch There is good confidence from developers that this failure is not due to the patch series, hence why I am filing it.

These seem to be hitting the same problem than bug 101309, it could be a dup.
