Yesterday I have found an unpleasent bug in OpenBSD.
I started two virtual machines in qemu with netbsd and building
source inside each virtual machine.
After about 10 min laptop become overheated just below the keyboard,
Xorg was shutdowned and host halted with following messages on console:
/bsd: acpithinkpad0: unknown event 0x6022
/bsd: acpitz1: critical temperature exceeded 100C (3732K), shutting down
Is described above load critical for openbsd?
What is an event 0x6022? I didn't find such event in dumped acpi tables.
You said that you felt heat just below the keyboard. As a tech, I know
that overheating can cause all sorts of random errors and will power off
your machine. Typically if it is strictly heat related, your pc will not
come back on for at least a couple of minutes, after it has had time to
cool off, or will power back on immediately and then power right back off.
Open your laptop if you can, clean dust off the fans and vents, and it
should help. I would also advise to get a laptop cooler - they are only
a few dollars and help a lot.
