Do you really need this options line? I am not sure about which SCSI
adapter you use. If it is a normal PCI adapter, even embedded and not a
single slot card, these options certainly cause errors. It was just an
example from modinfo I posted you before. It is often helpful to ask
google for information by other users if you have problems with special
hardware. It is good to know the whole and exact product name to search
for.

ramdisk did build properly

Ok, the problem is a ressources conflict. Maybe the options line I
commented above is causing trouble.

After loading the module properly, can you do a "cat /proc/interrupts",
"cat /proc/pci" (if it's a PCI adapter) and "cat /proc/ioports" to see
which hardware resources the SCSI adapter uses?

Thanks again,

The SCSI Adapter is an embedded Adaptec AHA274x on an EISA bus. It is dual channel with 8 36 GB drives attached.
