Subjectaic7xxx and 2.4.3 failures
Date
I've got a trio of identical PIII machines all failing with aic7xxx under
2.4.3. I've tried both aic7xxx 6.1.9 and 6.1.10 in addition to the one
in 2.4.3 (6.1.5?). These machines work fine under 2.2.18pre21.

I'm looking for any ideas or suggestions on how to fix this.
(Ok, honestly I'm hoping someone will say `you fool, read this message',
but I don't have high hopes for that.)

A typical startup with 6.1.9 proceeds like this... (6.1.10 hangs silently
after emitting the scsi0 and scsi1 adapter summaries, maybe it is
going through the same gyrations silently.)

SCSI subsystem driver Revision: 1.00

It repeats this for each ID for which a device exists. There actually
is a unit 0 and 1 on this bus. The error stream is slightly different
for unused IDs...

After failing on all 32 potential IDs at something like 47 seconds per
ID the boot proceeds and fails to mount the root partition which is on
these disks.
