Hello!

Tonight I had a kernel panic (full hang) with the following on the console:

CPU 0: Machine Check Exception: 0000000000000004
Bank 4: b200000000070f0f
Kernel panic - not syncing: CPU context corrupt

I tried to decode this:

# ./parsemce -e 0000000000000004 -b 4 -s b200000000070f0f -a 0
Status: (4) Machine Check in progress.

I've been searching for and found some additional info, it
looks like I'm not the first experiencing this problem:

http://kerneltrap.org/node/4993

Here ^^^ it is suggested that there was some thread about A64 MCEs
on LKML but I failed to find it so I decided to post... sorry if
it's redundant.

The kernel is 2.6.16-gentoo-r9 and the CPU is an A64 "Venice" 3500+
I can post further hw/sw environment information if req'd.

I had this same problem, search the lkml if you're interested in
investigating this further, I had the problem, was told it was
hardware, replaced my motherboard with the same model, the MCE
continued to occur, replaced the motherboard with a different model
and the MCE went away. It was some Biostar IIRC, but you can check the
archives if you really want to find out.

Good luck
