Crash/Reboot with Adaptec 3940UW

Calling all SCSI experts:
I have a bit of a challenge with an Adaptec 3940UW SCSI card. To start off,
here's the specs:
Tyan Trinity 1590 Motherboard v1.16
AMD K6 233MHz CPU
128M SDRAM
Windows 98 loaded on a Western Digital 4G EIDE drive (4 part VFAT)
Redhat 6 loaded on Seagate Cheetah (3 part VFAT, 4 part ext2, 1 part swap)
See below for more info
The Problem:
I was happily computing along, backing up my laptop to the /home partition
on the above machine (hostname = fuzzy) using rdist when fuzzy restarted.
This happened three times before I decided to do something else and work
on why later. The next day (I don't remember what i was doing), fuzzy
was rebooting into linux and needed to fsck the / partition (sda5). As
it was trying to fsck, it crashed/rebooted with no errors. Every reboot
has the same result. The only major change to the system was a
motherboard BIOS update.
Things I tried:
o Booting from Slackware 3.5 SCSI boot/rescue root floppies and running
fsck on sda5.
o Booting from Slackware 4.0 aic7xxx boot/rescue root floppies and running
fsck on sda5.
o When booting/rooting from floppy, I can mount sda5 but if I poke
around too much (cd's & ls's), it eventually crashes/reboots.
o I can fsck the other ext2 sda* partitions, but poking around too much
eventually crashes/reboots (tar'ing each partition causes a crash).
o Tar'ing a CD from either CD-ROM drive doesn't cause a crash.
o Setting Bus A termination to Disabled and Bus B termination to Enabled.
o I booted with aic7xxx=panic_on_abort,verbose and it still rebooted.
o I downgraded the motherboard BIOS to the original version and it still
crashes.
o Windows 98 (scarily enough) works fine. I did a thorough scandisk on
all EIDE & SCSI partitions with no problem. Both CD-ROM's work fine.
o The cheetah was repartitioned and installed with Redhat 6 a few weeks ago
and except when I had to turn off wide negotiation on the CD-ROM and Zip
drives, has been working fine.
At this point, I'm at a loss as to what to try next. Possibilities include
hardware failure on either the SCSI Card or Seagate Cheetah or a SCSI BIOS
mis-configuration, but then why does Windows 98 work? (No really, why
does Windows 98 work? :-) )
Any assistance would be gratefully appreciated!
Please contact me if there are any further questions via internet mail at
