Do you use the VGA/vidconsole at all?

A serial-only device (think soekris, ALIX/WRAP boards) that has no VGA
will have different requirements than a serial-only device will.

Your loader.conf statements are different than mine in the definition
that you have more than I do to enable serial.

My loader.conf just has one statement:
  console="comconsole"  - to feed ALL bootloaders, kernel probing, rc
startup on the serial device.  /etc/ttys defines the login lines.

Though trial and error, I found when you use a dual-setup:
"comconsole,vidconsole", the first one (comconsole) will get rc
output, and vidconsole won't.

Of course, you're on 8.0 and I don't run BETAs.  So the 8.0 BETA might
still be having com port oddities, plus I noticed your ttys line is
ttyu0, not ttyd0.  Did 8.0 change the serial line device?



To enable a serial-only device in my setups:
/boot/loader.conf:
  console="comconsole"

/boot.config:
  -D

/etc/ttys:
# enable serial line, cons25 or vt100, depending if I'm originating
from a bsd or windows box.



Enabling dual-setups should be just the loader.conf change to dual console.
