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?
