debian 2.4.18 fatal oopses (hardware related?)

[Greg Fischer]

Hello,
 
I have K6-2 based machine using an obscure motherboard which has been
crashing with seemingly increasing frequency (it happens almost daily
now). The motherboard is a California Graphics Photon 100 HC, that
company doesn't exist anymore. The oopses I get vary widely, but I have
attached a sample oops and its ksymoops output. They all ultimately end
up killing the interrupt handler. I am strongly suspicous of hardware
problems, but memtest86 ran for approximately 7 hours or so and didn't
find the memory at fault.
 
If there is any other information I should post, I'd be more than happy
to provide it.  Thanks.
 
the oops:
