That's shutdown -r, right? I don't have a real need for that,
so I am not sure I ever tried. But if I do what it says
"hit any key to reboot", it doesn't...

Sounds good, looks like the current issue might be affecting both
HEAD and 8.0_STABLE (with any luck it is the same problem.)

shutdown -p has always worked for me. Still does on my 8.0_STABLE
test system - but that has a much older kernel still...

*** FINAL System shutdown message from root%netbsd.noi.kre.to@localhost ***
System going down IMMEDIATELY
Feb 9 18:15:00 netbsd shutdown: poweroff by root:
System shutdown time has arrived
About to run shutdown hooks...
Saved entropy to /var/db/entropy-file.
Sat Feb 9 18:15:03 UTC 2019
Done running shutdown hooks.
Feb 9 18:15:08 netbsd syslogd: Exiting on signal 15
syncing disks... done
(that is back at the sh prompt on the Dom0).
I'll look see what intervening kernels I have lying around and try a
few of them - but one big clue from Greg's message is that the change
that matters is one that has been pulled up to -8 which should narrow
the field a little.
