I am finally unsubscribing from aic7xxx. I've been subscribing since I first sent this to you/aic7xxx on 1/24/00 :-)
I was hoping someone would have a similar problem, but never saw a similar posting.

I finally broke down and bought a new EIDE (UDMA) disk a-la-COMPUSA (really it is a MAXTOR 15GB UDMA33/66 for a measley $99.95 :-)

Well this fixed the kernel timeouts that I was getting with the Western Digital 6.4GB UDMA drives I had (both 26400 & 36400).

Conclusions:
=========

    1) This was not a Motherboard BIOS problem specific to the PA-2013
    2) Very unlikely a kernel or driver problem although it was not exhibited in the 2.0.3X kernels
    3) Not a problem specific to just any generic UDMA EIDE hard drive when mixed with my scsi (this is what I feared most!)
    4) Most likely it is attributable to the BIOS on the WD hard drive itself causing a BUS (or communication) problem with the
         IDE controller and/or Adaptec SCSI BIOS

Anyway, I am happy that I can use this new drive with a little more space than I had before and with the newer kernels.

Thanks for your help and your advise.

Hi Doug,

Recall I upgraded to the 2.2.14 kernel and even applied your patch <aic7xxx-5.1.22.patch> for the most recent driver and it did not cure  the problem?

We had a machine in here in the test lab with the same problem.  After
upgrading the kernel to a 2.2.14 or later kernel, the problem myseriously went
away.  We attribute it to IDE changes in the 2.2.14 kernel patch.  But, I'm
not an IDE expert....
