I've started experiencing this recently as well. X11 with cwm (no GNOME)
with Chromium running. Everything frezes, except caps lock LED works and
I can type `boot reboot` or `call cpu_reset` and system reboots.
Today's hand (I think it was) on:
OpenBSD 6.8-current (GENERIC.MP) #152: Thu Oct 29 15:48:34 MDT 2020
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
2020-10-30T14:03:48.738Z mbx-0013 /bsd: WARNING: / was not properly unmounted
2020-10-30T14:22:50.934Z mbx-0013 /bsd: WARNING: / was not properly unmounted

2020-11-05T13:50:58.049Z mbx-0013 /bsd: WARNING: / was not properly unmounted
Issues happend so far I think 4 times, around above timeframe, based on
reboots just after the hang.
When freeze happens I see only X11 output frozen, no output of panic
message or if I type (blindly, in ddb I think) bt, show panic, boot
reboot no output of those commands, so I cannot provide anything useful.
Any tips how I can capture bt, show panic or any other info?
Most annying part of this hang is, it affects Chromium in a way that I
loose last session information. Browser asks to restore session but my
tabs are gone and browser starts with no tabs or only few are restored.
My current dmesg is:
