uncorrectable machine check errors

Hello,

The server is the 2CPU AS2100 5/300 running du4.0d (patch set 1
installed) and the firmware is v5.1. Every once in a while it
is reporting uncorrectable "CPU Machine Check Errors" and the
CPU minor class is "660 Entry". Also, after the installation
of 4.0d and the patch set 1 the "110. Generalized Machine
State Type" appears during booting. It refers to a frame which
is not recognized.

I have tried hard to decipher the dia's output, but it seems I'm
missing something (or all of it). Is it memory or some other
subsystem? Is it the SWXCR which (as noted in the other message)
asks for a restart from time to time?

I'll attach 3 entries (sorry for wasting bandwidth) from dia.

It is interesting that the server didn't panic apart from one
last time when the panic string was "panic (cpu 0): System
Uncorrectable Machine Check 660". It has happened around 4:20AM,
at the time when the SWXCR is usually failing.

Thanks for your time.

Cheers.
