I get the same panic 100% of the time upon reboot. So I can quite
easily reproduce it. :)

I tried turning off softupdates on all partitions. Same panic. It also
caused umount to hang the machine. I don't have softupdates on / either
way.

I rebuilt a kernel today, about 1 hour ago. Still panics either way, with
or without softupdates.
