GPF under 2.0.35 while doing partition scan

I get the following general protection fault under 2.0.35 when I try to
boot the kernel on a Tyan S1668D system. This happends right during the
part of the boot that does the partition check.

I can boot the system from floppy (same kernel) without a problem and it
gets past this phase. Likewise I can move the HD to another exactly similar
system and it boots fine.

I have four Tyan S1668D systems, all with the same bios revision (5.01),
same bios configuration. All of them have the same video card (Diamond
speedster 64/ISA), all of them have the same BT-958 SCSI controller (same
bios revision and configuration (two per system). Plus all have the same
Ethernet card (DEC DE-500A).

I moved another running system disk from one of the other systems over to
this machine and the same thing happens. (Also tried re-writing the
partition
map on the drive to see if that helps, but it didn't). All drives have the
same partition map scheme. sda8 is the swap partition (128meg).

I have kernel debugging enabled but couldn't capture a trace before it
happened
so I manually typed in the below. Also attached is the complete list of
what
is compiled into the kernel but I really think it's got to be some strange
conflict with the hardware.. Hopefully someone here has a couple ideas?
