Xen has no panic= or panic_on_oops= command line options.

Please read the command line
documentation(http://xenbits.xen.org/docs/unstable/misc/xen-command-line.html). 
It is written and kept up to date for a reason.

Furthermore, you are force-overriding the normal reboot path with the
keyboard controller.  You shouldn't need to do this unless you have some
very wonky firmware.

Finally, I can't tell from your paste below, but ensure that you are
always using a debug hypervisor.
