the hardware is an older pentium (90?) it has 40 mb of ram with integrated
s3 video and uses a symbios scsi adapter with a 2.5gb hard drive. No
dump media is attached. The ethernet card is a i82557 mini-nic. I can
make this happen by usually accessing lots and lotsof data. For example
if i cat /dev/zero into a file then cat it back out a couple of times
it usually breaks. I swapped the scsi setup into another system (my
terminal actually), which does not have an integrated video controller
and the same type of nic. It had the same problem. The crash is known
to happen seemingly sporadically also.

is it worth reinstalling onto ide drives? I can backup all my changes
fairly easily.
