I've fixed this in upstream Xen quite recently, and haven't backported the patch to FreeBSD yet. I've now created a differential revision at: https://reviews.freebsd.org/D21028 With the fix. Feel free to apply it to your ports tree and rebuild xen-kernel, this should give you a working system. Roger.
