the problem:
---------------------------------------------------------
the system panics or freezes when accessing a ffs_fs
on missing geli-providers or missing geli-consumers (usb-
drive in my case).
if i unplug the usb-drive before umount/detach, geli
logs read/write-errors to the console (that's fine),
except for umount -f, that causes the system to freeze.
if i "geli detach -f" the geli-disk (sometimes needed
at shutdown, processes don't die and don't release fs-locks),
a chdir() to the mp will cause a panic, and a umount
(with or without -f) will cause the system to freeze
another problem with the panic: pressing any key to
interrupt auto reboot does not work - the keyboard locks up.
pulling an active usb-drive should not - but can - happen.

finally, a dmesg:

Trying to mount root from ufs:/dev/ar0s1a
--------------------------------------------------------------------------------
>How-To-Repeat:
1st, create and mount an geli-encrypted usb-drive:
----------------------------------------------------
plug in a usb stick
(kingston data traveler 256MB)
create a drive-key
(dd if=/dev/random of=/tmp/usb.key bs=1024 count=256)
init encryption
(geli init -v -P -a AES -l 256 -K /tmp/usb.key -s 512 /dev/da0)
attach the encrypted drive
(geli attach -p -k /tmp/usb.key /dev/da0)
newfs it
(newfs -o space -m 0 -n /dev/da0.eli)
mount it
(mount -o rw,noatime /dev/da0.eli /tmp/usb)
we want to auto-detach it on umount
(geli detach -l /dev/da0.eli)
-------------------------------------------------------
then either:
a)
pull the usb-drive
try a umount -f of the mounted drive
or b)
issue "geli detach -f " on the geli-disk before umount
and try to chdir() to or umount the mounted partition.
