Thank you very much for your suggestions! :-) The "Ctrl-a a" x3 works
well on the screen when the Xen kernel hasn't crashed, but didn't work
once Xen kernel crashed. :-(

I will put some printk in the machine_restart as Andrew suggested to
see if I can find more information. If you happen to know any other
ways that I can try, could you let me know?

Thank you very much!

Best,

Meng
