Hello team,

I've been using OpenBSD on this Thinkpad T410 for many years without
issues, but lately I noticed that it doesn't reboot properly, I don't
use it everyday, I couldn't say with which snapshot it started to
happen.

Running halt -p the machine powers off perfectly but running reboot at
the last moment in the halt process (screen already turned off) the
machine does not turn off, it hangs indefinitely, I have to press the
power button manually to turn it off.

Since it's a relatively old machine at first I though it was a hardware
problem, but I tried with Linux and it reboots normally.
