Well, I have the exact same adapter using the aha152x driver,
running under 2.2.12-20 (stock RH6.1 install). It's connected
to 5 SCSI CD drives in an external box, on a 7-plug 3-foot
50-pin SCSI cable with a Centronics adapter on the outside of
the SCSI enclosure. There's a 25-ping -> centronics cable
from the Adaptec to the SCSI box.
The only problem I've ever had with the setup was getting the
right values to pass to the module : once I had that working
the system worked perfectly.
The CD's don't seem to be recognised at boot either, and I
usually have to give them a quick nudge with 'mount /juke/cd0'
and so forth (they're in fstab), but apart from that, perfect.
So, I'd look to the disks themselves as the source of the
problem, or at any rate suspect them of uncovering a bug in
the aha152x code with some pretty unusual behaviour.
If you'd like me to run one of the disks on my system and
see how it behaves, I'll give it a shot.
