Hi,
I can reproduce this one at my will. If I shutdown to single mode, and
then do something in the lines of:
mount -ura; umount -a; mount -a; mount -ura; umount -a; exit
I get a couple device busy messages, ps axl only shows vinum daemon and
mgetty /dev/cuaa1

dmesg & trace attached. I have no idea on how to get any more info, will wait for instructions.
