3b1 crashing (kernel parity error)

[Rex Fowler]

For quite some time I've been having system crashes.  I've scraped the
connectors, blew out the dust bunnies, checked the power supply and
reseated the CPU.  The error messages don't show up in /usr/adm/unix.log, 
they just come up on the console as the system crashes.

John Milton's hardware notes explain how to find a bad chip but my
error messages are not of the same format as his example.  I have no
idea which numbers correspond to his examples.  John, can you help me here?

Below is a typical error report I get.  If anyone can make any sense out
of this I would be very happy.  It would be even nicer if someone could
tell me WHICH chip was bad but I can't be greedy :^)
