Sorry, I didn't understand it that way when reading the question the
first time. Yes, you should be getting some very quick Xen output before
starting the FreeBSD Dom0 (if your screen is slow when switching modes
you may not even be able to see it).

What's strange is that you don't get any output from FreeBSD when
booting as Dom0, can you paste the full contents of your /boot/loader.conf?

On my systems I see the usual FreeBSD kernel messages on the VGA display
even when booting as Dom0.

I think it may prevent the reboots, but as said, without knowing what's
going on this is just a wild guess.

Roger.
