Nobody has diagnostics that are any good.  In our case Unix uses lots
more of the hardware than any Diagnostic.  Diagnostics only seem to be
able to find really broken hardware.

This is a kernel panic because a parity error occured while executing in
the kernel.

Unix kernel lives up at the top of memory.  You could probably have moved
simm's or dips around until you found the problem if it was an oddending
component.  It might also be a slow bus tranceiver on the motherboard or
memory card.

Find vendors you can work with unless you are very hardware and software
savy.  You will save time, money and graying of the hair.
