I have an Intel NUC 5PPYB hooked up to an AOC 4K monitor. I tried to run kodi for the first time, added a video, and tried to play it. The console locked up hard. Mouse doesn't move and I cannot get to a virtual terminal either. I can still ssh into the system.

Eventually I see a kworker task blocked for a long time.

Video lockup is reproducible.

This may not be a kernel issue. Switching to wayland display server doesn't lock up this way.
