That's strange indeed.  What appears on the VGA console after this
line?  (If you can scroll back via Shift+PgUp.)

I've never managed to get the break through the hypervisor on a serial
port.  That means no sysrq for dom0.  That and the lack of flow
control make the Xen serial support unprofessional.  Those would be my
wishes for 3.4... :)

As you can see some kernel messages, it looks like you configured the
kernel console, contrary to what your config shows...
