Hi Andrew,
I thought I might find where the system got stuck.
As you suggested, I add several printks inside machine_restart();
If the machine restart when Xen kernel crashes, I can see the following output:
umount: /run/lock: not mounted
umount: /run/shm: not mounted

Hi all,
I'm trying to work remotely with the machine I have. So I want Xen
automatically reboot if it experiences a panic.
When Xen panic, it says " Reboot in five seconds...". However, it does
not reboot. :-(
*** The xen boot command line on my machine is ***
multiboot /boot/xen-4.6-unstable.
