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. -- Mvh Espen Fjellvær Olsen [EMAIL PROTECTED] [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
