I disabled sndiod, and unplugged my USB-to-3.5mm audio adapter and also
unplugged front 3.5mm audio port, then reboot my OpenBSD and waited on
xenodm login screen for few minutes; most of the time it reboots in
less than 10 minutes... without any interaction from me, or playing
anything...

It doesn't work at all. No input, no output. Even sndioctl will
freeze.
However when I plug my USB-to-3.5mm audio adapter, and run sndiod with
these arguments: -f rsnd/0 -F rsnd/1
I have audio output. However I don't have audio input for such a long
time, maybe 2 months (if it could help I can search for latest version
of kernel which my mic works with USB-to-3.5mm audio adapter).
With latest kernel front 3.5mm audio port works great, both as input and
as output; the only problem that I have with it is sudden reboots :(
