The machine locked up again, but without many output:

And after reset it got trouble during boot:
Configuration setting "allocation/zero_metadata" unknown.

Luckily it worked on the next attempt.

Neither do I.
I assume it's some sort of backport, since 5.15.0 has been quite stable:
reboot system boot 5.15.11-gentoo-p Sat Dec 25 00:18 still running
reboot system boot 5.15.0-gentoo-pa Sun Dec 19 11:46 - 00:13 (5+12:27)
reboot system boot 5.15.0-gentoo-pa Thu Nov 25 14:40 - 00:13 (29+09:33)
reboot system boot 5.15.0-gentoo-pa Thu Nov 4 10:23 - 14:35 (21+04:11)
