Can anyone provide any input as to the cause of the following errors 
on a FreeBSD 3.0-RELEASE machine?

During boot (or `dmesg'), the following is seen (note the erros at the
bottom):

------
bt0: <Buslogic Multimaster SCSI host adapter> rev 0x08 int a irq 10 \
	on pci0.16.0
bt0: BT-958 FW Rev. 5.07B Ultra Wide SCSI Host Adapter, SCSI ID 7, \
	192 CCBs
.
.
.

	Enabled

	Enabled
da1: 8683MB (17783240 512 byte sectors: 255H 63S/T 1106C)

(pass0:bt0:0:0:0): RECOVERED ERROR asc:1c,0
(pass0:bt0:0:0:0): Defect list not found field replaceable unit: 18 \
	sks:ca,2
------

Then, occasionally the following repeats on the console:

------
Jan 26 16:45:32 fern /kernel: (da0:bt0:0:0:0): \
	WRITE(06). CDB: a 13 48 40 10 0 
Jan 26 16:45:32 fern /kernel: (da0:bt0:0:0:0): \
	Deferred Error: HARDWARE FAILURE info:135070 asc:3,0
Jan 26 16:45:32 fern /kernel: (da0:bt0:0:0:0): \
	Peripheral device write fault field replaceable unit: 8 sks:80,1
------

The machine and disk are only a few days old... I would normally guess
a bad disk but this is my first installation of 3.0 with the new CAM
scsi code. Any thoughts?

Thanks.

Chuck
