I'm getting the following panic shortly after boot when I build
unstable tip with debug=y.  I took a glance at the code, but I have no
idea what the code is supposed to be checking for... anyone?

I'm running x64, on a tip linux- kernel, with a Debian 4.0
filesystem.  There is a restored HVM domain running at the time.
