I'm having SCSI-related problems on the home PC, which has run fine for three
years now whithout being hardware-upgraded. I update the system on a regular
basis, though (last buildworld/installword was on Thu Dec 26 2002).
The IBM drive fitness test showed that hard drives are ok. The error seems to
appear randomly, whithout particular conditions (load avg, used mem, programs
running, etc.).
A couple of days ago the SCSI bus has been reset five consecutive times! Is it
time to change my AHA2940 or this has nothing to do with the SCSI controller?
