[Xen-devel] refcount errors then crash on XenoLinux with the latest source

[Kip Macy <kmacy@xxxxxxxxxxx>]

I had just tested my domain builder for the nth time on xeno-unstable
(very latest source), when I saw the messages below on the console.
DOM0 no longer responds to ping - I'm hoping that it will recover,
however, in all likelihood I will be hitting the rpb in a few minutes.
