Recently, I installed NetBSD 1.3 on a Quadra 605 (with FPU), and I'm
experencing an anamoly that I'm not quite sure how to resolve.  The
following message lines keep appearing (although numbers are not always the
same).

Mar  6 13:39:40  /netbsd: dmaintr: discarded 32 b (last transfer was 1008
b).
Mar  6 13:39:40  /netbsd: esp0: !TC [intr 10, stat 87, step 4] prevphase 0,
resid 3f0

When booting in single user mode, it happens only occasionally.  When in
Multi-User, this message will appear every 30-120 seconds, sometimes
several at once.  Happens regardless of what I'm doing--running a program,
doing somethin at the command prompt.

The message lines seem most prone to appearing when a SCSI transaction is
taking place.  NetBSD is installed on a Syquest EZ135 removable.

Would presuming that there is a misconfiguration in either disktab, the
disklabel, or fstab be  correct?  For the sake of keeping this to a
reasonable length, I'll include only fstab and the disklabel.  If more info
is needed, I can supply that too.  I'm using the Generic 1.3 kernel.

Fsck also reports that the disk is getting trashed alot.  (Unallocated
blocks, unknown files).  I've already tried reformatting and re-installing.
Any help would be deeply appreciated.

Fstab:
/dev/sd1a	/	ffs	rw 1 1
/dev/sd1b	none	swap	sw 0 0
kern		/kern	kernfs	rw 0 0
proc		/proc	procfs	rw 0 0
