How old is your xen-unstable? And how did you build it?

 1. It appears to have assertions compiled in, yet it's not a debug build
(debug=n). This is weird.
 2. You have the function __bug() on your backtrace. Current xen-unstable
does not use the __bug() function.

You probably need to upgrade and do a clean build.
