Problem: Computer _sometimes_ stops after the "Mounting root from
ufs:/dev/ad0s2a" line.
Running Current, built world yesterday. (Problem appeared fairly
recently (as in ~2 weeks?, but didn't have ddb in previous kernel)

dmesg:
[...]

[ctl-alt-delete], reboots and then boots ok, mounting /dev/ad0s2a with
no problem.

Need more info? (this is fairly new to me...)
