Hello,
My Gentoo box has recently started spewing out Machine Check Exception
errors to my log files. They're correctable, and the machine appears to
be running OK, but I'm just wondering if this is a foreshadowing of
impending doom.
I get four repeating MCE errors, from the moment the system starts up.
I've run memtest86 for hours and it shows no error. I'm having a hard
time figuring out what exactly the error is. Nothing is overclocked
and the system is not overheating as far as I can tell. It's a 2.0 GHz
Celeron in an Asus Pundit with latest BIOS.
Here are the errors, followed by the parsemce output. Any ideas?
