8.1-STABLE amd64 machine check

[Dan Langille]

I am encountering a situation similar to one reported by Andrew Heybey 
at http://docs.freebsd.org/cgi/mid.cgi?6E83197B-9DD5-4C7E-846D-AD176C25464D

This morning I found this in my /var/log/messages:

Andrew: You posted about this on July 14.  Anything new since then?

John: Is it time for me to get a new CPU?

thanks
