[wellylug] hardware errors

[kingsley at loaner.com]

Hi Richard,

I searched Google's indices for the error messages
you wisely linked to.

Evidently 

    they're called "Machine Check Exceptions",

    they can be caused by a bad CPU, and

    a package named "mcelog" can collect and
    decode them.

I hope that helps,
Kingsley
