So, I tried booting from the old kernel again, and then did a
'freebsd-update rollback', and that worked just fine. I thought I'd
try again, but first did a 'freebsd-update fetch' and 'freebsd-update
install' to get the latest 8.1 updates.

That worked just fine, so I did a 'freebsd-update -r 8.2-RELEASE
fetch' again, then a 'freebsd-update install', which went just fine,
and after that rebooted as directed to attempt the second
'freebsd-update install'.

That's when the same thing happened - i got dumped into the mountroot
prompt again. And, again, rebooting and escaping to the loader prompt
allows me to unload the kernel, load /boot/kernel.old/kernel then
autoboot, and boot up. Same as before.

Any thoughts?
