Actually it's easy to panic DragonFly (or FreeBSD, last I checked,
which was early 5.x) by pulling out any USB device while it's in use
-- not necessarily a storage device, it happens for me with a
USB-to-serial convertor too, and used to happen under FreeBSD with a
USB audio device. Annoyingly the USB audio device was often not
actually in use (no audio playback/recording happening, no mixer
program running), but the kernel still believed it was in use and
refused to "detach" it even though it was physically gone. The panic
happened if I plugged it in again.

The response I got on the FreeBSD lists at that time was it would
involve major rearchitecting of something else (not VFS) since the
kernel assumes that a device, once detected, will always be there and
will not be abruptly yanked out...
I don't know if this has changed lately.
