I have the same problem with a USB/IDE drive, and a SmartMedia reader.  If
they are mounted at shutdown, when the system halt script gets to "Sending
all processes KILL signal", it seems the process [usb-storage-0] (and -1)
gets killed, end of communication with the drive - so it can't be unmounted
cleanly.

Shouldn't the [usb-storage-x] processes be immune to this signal?
