Subject: [drm_wait_one_vblank] WARNING: CPU: 0 PID: 269 at
drivers/gpu/drm/drm_vblank.c:1084 drm_wait_one_vblank+0x160/0x170 [drm]
Hello,
FYI this happens in mainline kernel and at least dates back to v4.13 .
It has been reported before, well sorry, if cannot be fixed or
work-around, it'll keep popping up in our tests and consume our time.
The last resort would be to blacklist this error from future 0day
reports.
