mpt(4) iuCRC errors

[Joshua Boyd]

Hello all,

I'm receiving iuCRC errors pretty constantly after rebuilding from a
December kernel/world to yesterday's source, like the following:

mpt1: EvtLogData: IOCLogInfo: 0x31181000
mpt1: 	EvtLogData: Event Data:  00000006
mpt1: mpt_cam_event: 0x1
(da6:mpt1:0:6:0): READ(10). CDB: 28 0 8 20 ae d7 0 0 40 0
(da6:mpt1:0:6:0): CAM status: SCSI Status Error
(da6:mpt1:0:6:0): SCSI status: Check Condition
(da6:mpt1:0:6:0): SCSI sense: ABORTED COMMAND asc:47,3 (Information
unit iuCRC error detected)

I was not receiving these errors previously. I recompiled to newest
sources only to add support for mps(4) since I've got a supported card
on the way.

I also received these errors on boot for every drive (across 2
controllers), but that may have been related to enabling smartd at
boot.
