I didn't miss it. But your problems didn't seem to me to be related to the
sym53c8xx driver nor to the SCSI layer given your 'no message output to
log' observation. SCSI errors usually trigger timeouts and resets that
are very verbose (may-be too much).

Do you really want to do that ? :)
I would suggest to to try different kernel versions, preferently stable
ones: 2.2.X). If you want to give a try with 2.3.X series, you should
preferently try something close to 2.3.51 but probably not an higher
version. You may report differences if any.
