I think it might be a side effect of some MSR cleanup patches in the
hypervisor, and pribably not related to your hang. You'll need to track down
where your guest kernel is hanging. Add some early printks or maybe use the
xenctx tool to get an EIP value and map that to a location in the kernel
code.
