What exactly is being reported here? If there's a regression after a kernel
update, please provide a bisect between last known good and drm-tip.

There's nothing MDAPI related in the kernel and you're not specifying any link
to the testing suite, so this bug report is hardly useful.

Providing a dmesg with debug options from running just the failing subtest
would be a good start to guess something.
