, it seems to be related to ncr53c720 driver.
That's the second hit on that driver this week:
http://lists.parisc-linux.org/pipermail/parisc-linux/2006-August/030054.htmlIn the above mail, the driver was reporting:
ncr53c720-0: rev
0xfirq 66
ncr53c720-0: ID 7, Fast-10, Parity Checking, Differential scsi0 : ncr53c8xx-3.4.3gVendor: SEAGATE Model: ST15150W Rev: HP07
Type: Direct-Access ANSI SCSI revision: 02

Where the model number was single-ended, not: ST15150WD (Differential) and the problem was that the drive could not be written.
Joel, what does that part of your dmesg have to say?
That said on my C110 I got:
--- snip ---
ncr53c720-0: rev0xfirq 66
I could not find any code that identifies the actual chip, the "ncr53c720" seems to be hardcoded in the message.

ncr53c720-0: ID 7, Fast-10, Parity Checking, Differential
This message is part of the strange SE/DIFF code.

scsi0 : ncr53c8xx-3.4.3g
Vendor: SEAGATE Model: ST34371W Rev: HP03
Type: Direct-Access ANSI SCSI revision: 02
And even though this is a different model drive than Joe's problem, it is still claiming to be SE:

Hmm... I forgot to check if the string is long enough for 9 characters, perhaps just the "D" is getting clipped in the message.

target0:0:5: Beginning Domain Validation target0:0:5: asynchronous
target0:0:5: wide asynchronous
target0:0:5: FAST-10 WIDE SCSI 20.0 MB/s ST (100 ns, offset 8)
And that is just wrong - the drive is a SCSI-3 (Ultra SCSI) (Fast-20) but this drive can fall back to FAST-10, which may be what is happening.
Hmm... Maybe Joe's drives can't fall back to match the controller.
See page 15 of:
<http://www.seagate.com/support/disc/manuals/scsi/67491d.pdf>
Just more reasons to /dev/null this driver.
Mike
