My headless build machine didn't have a problem, but my laptop (which
was running Xorg (built under RELENG_6; I have the misc/compat6x port
installed) seemed to have a problem when I tried to login, so I rebooted
it with a serial console attached. Second time around, it booted OK,
but when I issued
sudo boot0cfg -s 1 ad0 && sudo reboot
I saw the following panic (cut/pasted from serial console) -- I'll prepend
a bit of the boot stuff for context:
