scsi drive recognition problems

[taren@c719777-a.frmt1.sfba.home.com]

I've been having problems when (re)installing the Debian distribution using
the 2.0.8_1998-06-23 *14* installation disk images.

On two different systems, with two different Adaptec controllers (AHA-2940AU
and AHA-7880), I have had major problems getting the rescue disk to recognize
my second scsi drive.

I have not had this problem (at all) with the 2.0.6_1998-05-12 distribution
disks.

At times, I have had to revert to using the 2.0.6_1998-05-12 set, rather than
use the newer 2.0.8 set (it's only been recently - and even then, with 
difficulty [I get timeout errors, if the second drive is recognized at all]) 
to get both disks to be 'seen' by the installation media.

I am using one IBM DCAS-34330W, and one IBM DCAS-34330 (drives a and b in that
order).

I don't know what the problem is, other than maybe a 'newer and better' 
aic7xxx driver being used.  There are no errors generated when the second
drive isn't found; only when it is, and then (sometimes) timeout errors.

If anyone has any suggestions about how to 'fix' this, I'd appreciate it if
they'd let me know.

Thanks,

Richard Paynter
