Cat /proc/scsi/scsi

You might wish to check for module errors with

modprobe -vn aic7xxx

After doing so also check /var/log/messages. Please post any related errors here...

Try adding this line to the /etc/modules.conf file and restarting:

options scsi_mod max_scsi_luns=128

Also, please dont forget to post the output of

cat /proc/scsi/scsi

Strange that it doesn't see a module that later it claims it's using...

In the meantime I also searched some forums again and read somewhere
from a few users that they had to switch back to the old scsi driver to
be able to access scsi drives.

As far as I understood, somewhere between linux-2.4.x and linux-2.6.17
the scsi driver was replaced by a new one. But the old can be compiled
in using appropriate config flags when doing the kernel config.
