hi,

OpenBSD started to crash in a VM running under Qubes OS after they upgraded something in their emulation stack, other OS still work AFAIK. I don't know if it's an OpenBSD issue, I already reported it upstream on GitHub but I thought this may be useful to report the issue here as well => https://github.com/QubesOS/qubes-issues/issues/8502

When trying to boot cd73.iso from 7.3 amd64 or cd73.iso from a snapshot of today, there is a panic trap type 4 (see 7.3-error.png).

When trying to boot a previously installed OpenBSD that's running a snapshot from end August, I get a different error (see current.png):

kernel: protection fault trap, code=0
Stopped at      tsc_identify+0xdf:      rdmsr

I found a related bug on bugs@ but it was a combination of AMD CPU + vmm bug https://marc.info/?t=166721638200001&r=1&w=2

My hypervisor with the issue has a Ryzen 5 5600X, I tried on a i5-7300U without any issue.
