AMD Athlon MP Machine check exceptions

AMD Athlon MP Machine check exceptions

[Dr. David Alan Gilbert]

Hi,
  Is there any information on decoding AMD Athlon MP Machine
check exceptions?  I can't seem to find the appropriate AMD
document on their website - it would be nice to know
if this is RAM or cache or something else that gave it.

The error reported is:

Jul 19 21:07:37 gallifrey kernel: MCE: The hardware reports a non fatal,
correctable incident occurred on CPU 0.
Jul 19 21:07:37 gallifrey kernel: Bank 2: 940040000000017a

Thats from 2.5.75 on a dual Athlon MP on a Tyan 760MP motherboard.

The machine has apparently been running fine for some time now - perhaps
this is heat related due to the unusually warm weather over here,
or perhaps it is the machine check polling picking
up something that has been going dodgy for a while.

Hi !

You should feed it through Dave Jones' parsemce program. BTW, he already
replied a few months ago to exactly the same report (search 940040000000017a
on google, you have it already decoded :-))

Cheers,
Willy

Thank you! Unfortunatly Dave's site seems to be down at the moment
(and google don't seem to have it cached - why?)

Ah - I hadn't thought of searching for the hex, I'd presumed that
related to a particular bank/address/cache line and the chances of lots
of people hitting the same one would be slim - unless there is a
problem? Perhaps when I get parsemce it will be clearer.

Gah, a pox on Cobalt Raq's...
Such problems always seem to happen when I'm a few thousand miles
away from said box also, so I'm not really too sure whats happening
with it right now..  
When I get chance, I'll move it (and post-halloween and other bits)
to kernel.org.

Beats me.
