Subject: Machine Check Exception on Opteron 265
Date: Sat, 14 Apr 2007 16:58:43 +0200	[thread overview]
Message-ID: <4620EC23.4010404@mrfjo.org> (raw)

Hi!
Today our Opteron 265, 2x2, paniced after many months uptime, giving
only this error message:

HARDWARE ERROR
CPU 2: Machine Check Exception:            4 Bank 4: b60a200100000813
TSC 6bb9fd0142921a ADDR a891e9b8
This is not a software problem!

mcelog --ascii gives this on the above error:

HARDWARE ERROR
CPU 2 4 northbridge TSC 6bb9fd0142921a
  Northbridge ECC error
  ECC syndrome = 14
       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 b60a200100000813 MCGSTATUS 4
This is not a software problem!


As far as we know there wasnt any unuasal activity on the server at the
time.
We updated glibc yesterday, but that shouldnt really cause such a problem.
So now we wonder if this might be an MCE bug, or really a HW problem,
and if it is one of the CPUs, or the RAM thats faulty.
We are running 2.6.18.
