I can refine my previous comment:
There is nothing special in /var/log/messages There is nothing special if you run journalctl as root
But if I run journalctl as my non-root user, I find a lot of lines like these at the time of the crash:
Nov 15 09:54:13 localhost.localdomain pulseaudio[2085]: [alsa-source-92HD81B1C5 Analog] asyncq.c: q overrun, queuing locally Nov 15 09:54:13 localhost.localdomain pulseaudio[2085]: [alsa-source-92HD81B1C5 Analog] asyncq.c: q overrun, queuing locally Nov 15 09:54:13 localhost.localdomain pulseaudio[2085]: [alsa-source-92HD81B1C5 Analog] asyncq.c: q overrun, queuing locally Nov 15 09:54:13 localhost.localdomain pulseaudio[2085]: [alsa-source-92HD81B1C5 Analog] asyncq.c: q overrun, queuing locally Nov 15 09:54:24 localhost.localdomain pulseaudio[2085]: [alsa-source-92HD81B1C5 Analog] ratelimit.c: 110 events suppressed
However, I guess these errors are a consequence of the hang, not the cause.
