Sorry, I forgot to mention in my previous message that the output I copypasted was not from a VM, but from a real computer under my desk.

In this very same machine, I get the error

procmap: /dev/mem: Operation not permitted
no matter the option I give to procmap. I vaguely recall this command working in the past.

@angel Thank you for that clarification. Wonder what the issue is here ...

That narrows it down to either some type of BIOS/UEFI memory setting or a bug on OpenBSD. 🤔

It's the first time that this happens to me with my first 7.2 installation.

procmap seems to be an indicator for that bug.
Edit: I was wrong about procmap. marc.info/?l=openbsd-cvs&m=147

Interesting. It seems you also cannot execute as root

sysctl kern.allowkmem=1
You must put it in /etc/sysctl.conf.

This is probably common knowledge for OpenBSD superusers, but I'm still a bit of a newbie here.

Thanks for the clues!
