Hi -- you have a serious HW problem.

Fix your hardware.


Comment 2 Peter Murphy 2009-09-10 13:52:50 UTC

I am not sure there is a problem with the HW as the errors dont exist on RedHat 4.4.


Comment 3 Prarit Bhargava 2009-09-22 15:51:30 UTC
5.4 included a revamped mcelog package that (in theory) reports more errors than previous versions.
