I rebuilt the FreeBSD 10.0 kernel, found it can't load my mobile disk:

(da0:umass-sim0:0:0:0): ATA COMMAND PASS THROUGH(16). CDB: 85 0
8 0a 00 00 02 00 00 00 00 00 00 00 40 ec 00
(da0:umass-sim0:0:0:0): CAM status: CCB request completed with an error
(da0:umass-sim0:0:0:0): Retrying command

The shutdown will be paused by it. When I pull out the mobile disk,
the computer is shutdown normally.

This is the information when I insert the disk:

ugen0.4: <vendor 0x05e3> at usbus0
