Hi Tony,

Not easily, and it's too late to parse
arch/x86/kernel/cpu/mcheck/mce_64.c and find out what it means before
I nod off. Still, before I sign off, have you tried running "mcelog
--ascii"? It needs to be run on the machine the check occured on. It
might give you something to go on before the cavalry arrives.

Best regards,
  Jeroen.
