I found that "no_timer_check" option earlier in the m00nbsd.net site
and did tried it:

    linux root=/dev/vda1 ... no_timer_check

Yet I gave me the same error... I tried different combinations as well:
"noapic" + "no_timer_check", "noapic" + "nolapic" + "no_timer_check",
"nolapic" + "no_timer_check" and "acpi=off" + "no_timer_check". But
everything resulted in the same kernel panic message.

By the way, I downloaded a NetBSD and OpenBSD live image copy just to
see, and they did work pretty well. I was able to transfer certain
things from my usual Artix Linux box to NetBSD. However, certainly I
cannot entirely drop Linux because I do still require using certain
hardware there using hardware passthrough.

Regard that "curious" dmesg. I just recently noticed it won't appeared
again.  Perhaps it's a thing that occasionally happens. kern/57985 does
mention it as "spurious". Maybe it's nothing to worry about at all as I
supposed.
