Several years ago I ran into a problem with similar symptoms on an old
Adaptec AHA-154X controller. Files (and most certainly "file systems"
if I had persisted) on my hard disk were getting corrupted in random
places with constant length strings of garbage. This turned out to be
an inappropriate setting for the AHA1542_SCATTER constant: it *was* 16,
and setting it to 8 fixed my problem. I'd look for a similar "#define"
in the header file for your SCSI device driver and try cutting the value
by half. Why "half"? No justification other than it worked for me, and
it's a power-of-two kind of thing that hardware seems to like :-).
