MCE Analysis Help

idata — Wed, 27 Jun 2012 15:54:33 GMT

Any ideas where I can get some help with the analysis of the MCEs below? Using an "unqualified" OS (CentOS), which my OEM vendor doesn't support and therefore doesn't have the support pack tools that hook into the OS for analysis. They suggested I "ask Intel" to provide an analysis of what part of the subsystem may be having the problem. OEM vendor is suggesting this is potentially not strictly a hardware error despite what the MCE says, and might actually be an interop problem between the OS and the hardware. These are IA64 systems, and I'm seeing them occur regularly on multiple machines.

Thanks in advance,

Please let me know what is the Kernel that you are using?

Also let me know the processor model that you are using, and if possible the system configuration itself (hardware components)

Please bear in mind that Intel desktop motherboards do not support Linux operating systems, so we should check for this type of issues on Linux forums.

Adolfo,

Thanks for your response. I'm getting the exact Kernel version info on the CentOS build now, and will reply with that shortly. The system is an HP Proliant DL360cG7 with the Itanium IA64 (Westmere) processor; so not a desktop motherboard. Red Hat Linux is a supported OS on this box, and CentOS is essentially an open-source version of it, but not one that HP officially supports, which is why I'm posting here. I'll have more information on the exact configuration of the box shortly.

I did find the following document on IA64 MCE codes, and am attempting to understand it now: http://www.intel.com/Assets/ja_JP/PDF/manual/253668.pdf http://www.intel.com/Assets/ja_JP/PDF/manual/253668.pdf
