What does this error mean?
CPU 0: Machine Check Exception: 0000000000000004
Bank 0: 820000001040080F
I have a Matsonic 9097c motherboard, 2.4Ghz prescott celeron cpu. This
error seems to be random. We have replaced the motherboard & cpu to no
avail.

It normally indicates a hardware problem. The precise meaning of all the
bits is in the Intel chip docs (volume 3). If you've swapped the
mainboard/cpu it might just be bad RAM.

He can also get precise info with Dave Jones' parsemce tool :
http://www.kernel.org/pub/linux/kernel/people/davej/tools/
It currently says :
Status: (4) Machine Check in progress.
Restart IP invalid.
parsebank(0): 820000001040080f @ 0
External tag parity error
CPU state corrupt. Restart not possible
Bus and interconnect error
Participation: Local processor originated request
Timeout: Request did not timeout
Request: Generic error
Transaction type : Invalid
Memory/IO : Other
Since it says it's neither memory nor I/O, I think it might be related to
a PCI parity error with some card, either during transfers or config access.

Thats the interesting part, I have 2 cards plugged in... 1 x SIS6326 AGP
graphics card, and 1 x Connexant PCI modem card.
If I put the modem card into the left most pci slot, I get a bios IRQ
routing error.
I've replaced the AGP card with another make, same problem, I've had my
supplier replace the motherboard, same problem. Replaced the CPU, same
problem.
I'm going to take the system back to the supplier tomorrow and ask him
to sort it out.... I'm not going to tell him anything apart from "It
does not work", its useless explaining to him the above if he not going
to understand a word of it.
Could this be an incompatibility issue between the CPU and the mobo?

Nigel
