Subject: 5.10 regression: hang at shutdown, DRM or ALSA suspected

Hi,

I have an Intel NUC D54250WYK which no longer shuts down properly after
moving from 5.9.16 to 5.10.4, because systemd hangs. The kernel logs
make me beleive it is likely a locking issue in either DRM or ALSA or
both. Relevant messages which I could extract from the journal:

Jan 05 22:21:38 host systemd[2664]: pulseaudio.service: State 'stop-sigterm' timed out. Killing.
