Hello.

I am trying to diagnose my old Debian (Kernels v2.6.30 and v2.6.32) that is having random and rare kernel panics and a lot of hardware errors with my Athlon 64 X2 CPU (you can see mcelogs in http://pastie.org/867602 for the whole filtered logs). I want to reproduce it outside of my Debian with KNOPPIX v6.2.1 CD, but cannot seem to reproduce this in KNOPPIX v6.2.1 CD. Same for memtest86+ v4.00 on a 3.5" boot disk. I need to confirm that this is really a hardware problem or a false alarm in my old Debian (had it installed since 9/24/2004 and kept it updated for many years).

However, KNOPPIX tells me it cannot open /dev/mcelog after installing mcelog via apt-get command. Am I missing something? I didn't see anything machine errors in regular dmesg overnight (only a few hours).

Thank you in advance. :)

No one knows? I tried Ubuntu liveCD, but can't find a mcelog package to install it. :(

Did you use Ubuntu 64bit (AMD64) 10.04RC? I saw /dev/mcelog and executed the command mcelog. There was a message that mcelog could be installed with

sudo apt-get install mcelogbut you have to enable the component called "universe" first. Somewhere I read that mcelog does not work with 32 bit Linux because of incompatibility with old cpu types.

It was v9.10 stable for sure. So, is this 64-bit requirement for 64-bit hardware only or does kernel have to be 64-bit too? On my old Debian box, I use i686 (32-bit?) kernel and can use mcelog.

I wonder why KNOPPIX doesn't work? 32-bit?
