hi all.
i got a panic when attached and then detached the ubt0 device just
after a few seconds.
Actually, it is a built-in bluetooth device in my laptop, operated with
the Fn key.
The module was loaded via
ng_ubt_load="YES"
in loader.conf

Since ng_ubt is a BT-USB interface, there is nothing extraordinary
in the above, i think. Though, maybe it is related to usb, not ubt.
This is the first time i got this panic. Usually (i.e. until this
time) there was no panic related to ubt0. So, probably it is not
reproduceable :(
Unfortunately, the kernel didn't have any debug options when it
occurred.
thanks.
