   I thought it was ok with a 2.4.5-ac kernel however it started
acting up again today giving more i/o errors.  I think I'm just going
to give up on these boards as I have 3 of them doing the exact same
thing.  However they are flawless in up mode.

   It seems to be ok with 2.4.5-ac19, so I guess I'll just wait for
2.4.6 and hope that resolves it for good.

First, I copied 640 Mb file to the jaz disk, no problem. Then I ran the
same commands you did, also no problem...

That would imply, at least, that the SCSI drivers are not at fault here.

I realized that after I sent the message. Doh!

I have an AIC7xxxx based SCSI card in my machine as well, hooked up to a
Jaz. I haven't actually used it in ages, but I'll test it to see of the
problem is apparent on CUV4X-D board as well.

Thanks for the tips, however it doesn't help :-(

Anyways in case anyone is curious the i/o problem still happens
with an aic7xxx card put in and the onboard scsi disabled.

Already set at 1.1

Asus CUV4X-DLS

There seems to be a major problem with this board and 2.4.x kernels.
I consistantly get SCSI Input/Output errors on multiple drives that I
know are good when running a SMP kernel.  These errors do no happen
with a UP kernel.  This is happening on multiple systems and with
multiple know good scsi drives of all speeds and sizes.

Test#1:

2.4.2 (redhat 7.1 version)

dd if=/dev/sda of=/dev/null
(fails with input/output error)

Test #2:

2.4.2 (redhat 7.1 version)
noapic on boot

dd if=/dev/sda of=/dev/null
(fails with input/output error)

Test #3:

2.4.2 (redhat 7.1 edition)

dd if=/dev/sda of=/dev/null
PASS!
