Hi Pluggers,
I assumed this is a Xeon processor.
It could be a failure processor and affects the channels of memory banks that
link to it. This is the difference of Xeon to Itanium. If Xeon proc fails or
one of the core fails server halt and it won't start.
Regards,
Boker

Hi!
Yesterday one of our servers had this on the console:
[ 1184.087973] mce: [Hardware Error]: CPU 0: Machine Check Exception: 4 Bank 8:
ba000000000000b2[ 1184.087973] mce: [Hardware Error]: TSC 3a3965b65c0 MISC
80000[ 1184.087973] mce: [Hardware Error]: PROCESSOR 0:206c2 TIME 1477301538
SOCKET 0 APIC 0 microcode 2[ 1184.087973] mce: [Hardware Error]: Machine check:
Processor context corrupt
So I did some research and found out that I can use an app named mcelog to
decode this. ?This was the output from it:
Hardware event. This is not a software error.CPU 0 BANK 8 TSC 3a3965b65c0?MISC

So my question now, for those who know more about this area than I, is: ?Is the
exception due to a problem in the CPU itself or somewhere on the motherboard?
Regards.
