>Description:
	System locks hard when trying to upload file on mobile phone
	using obexapp via ubt kernel module.
>How-To-Repeat:
	1. kldload ng_ubt
	2. /etc/rc.d/bluetooth start ubt0
	3. obexapp -a whateverphone -c -C FTRN
	4. obexapp will allow to browse files on the phone, do cd to some dir
           and do 'put /some/file.txt'
	5. The following messages appear on the screen:
		ubt_bulk_out_complete2: ubt0 - Bulk-out xfer failed. IOERROR (13)
		ubt_bulk_out_complete2: ubt0 - Bulk-out xfer failed. SHORT_XFER(16)
	System is locked. Doesn't response locally or via ssh. Replies to ping
	however. Ctrl-Alt-Esc doesn't break into ddb too.
