shutdown -r / shutdown -h / reboot all hang and don't cleanly dismount

I dunno about firmware, but you can smack 'em with a big hammer...

/etc/rc.local:
for i in 0 1; do
    /sbin/camcontrol cmd ada${i} -a "EF 85 00 00 00 00 00 00 00 00 00 00"

LCC was somewhere in the upper 400's (I wanna say 480-some?) a year
