Hello,
can some kind soul please shortly explain what this message tells me:
HARDWARE ERROR
CPU 1: Machine Check Exception: 4 Bank 4: b60a200170080813
TSC 89cfb4725b17 ADDR 1025cb3f0
This is not a software problem!
Run through mcelog --ascii to decode and contact your hardware vendor
Kernel panic - not syncing: Machine check
Of course I ran mcelog but I don't quite understand how the additional info
helps me finding the problem.
Is this a problem with RAM? And if, which one?
The box is a dual opteron with two banks of mem (4 sockets each), each socket
holding a 1 GB mem module.
Thanks for any hints.

It sounds like a memory error, but there are some other bank4 errors that
can crop up. What does mcedecode say?

Since when is linux-kernel your hardware vendor?
Would it help if the message was written all upper case?

Well, here it is:
HARDWARE ERROR
CPU 1 4 northbridge TSC 89cfb4725b17
Northbridge Chipkill ECC error
Chipkill ECC syndrome = 7014
bit32 = err cpu0
bit45 = uncorrected ecc error
bit57 = processor context corrupt
bit61 = error uncorrected
bus error 'local node origin, request didn't time out
generic read mem transaction
memory access, level generic'
STATUS b60a200170080813 MCGSTATUS 4
This is not a software problem!
Is this some sort of mem error?
Thank you for your help

I got a very similar error on a supermicro H8QC8+ (4way dual-core opteron)
during heavy disk writes. It only happened once so far. The error message also
mentioned
4 Bank 4: b608a00100000813 (strange that the last 4 digits agree).
