I spoke too soon.  The latest from Linus' tree also freezes... but it
took overnight to get there.  There was no particular load on it.

This system was previously running 2.6.22.y w/o problems with a similar
kvm pattern.

This time it froze w/o showing any kvm rdmsr messages.  And while it
froze sometime over night, I cannot be sure when.  Here is the SysRq's
"showPc" output:

Are there things I should be looking for?
