There is a xenbus device still present and during shutdown it is trying
to set it to CLOSED but at this point xenstored isn't running and the
xenbus write stalls.

Do you have VMs that are still running when you attempt a reboot?  If so
shutting them down will likely avoid this.

Can you provide the output of xenstore-ls prior to attempting a reboot?



I though Xen init.d scripts would stop all of them before rebooting? Here's the output of chkconfig and xenstore-ls:
