I added panic=5 to the linux kernel arguments which has had the
desired effect, unfortunatly despite the serial console working with
Xen and Linux it appears to not work with grub, I copied the grub
serial config from my main workstation so I am sure the config is
correct as it works on that system, but on this Dell Optiplex 755 I
get no grub menu over the serial console, just the Xen & Linux dmesg,
oops, and reboot, so the machine is now stuck in a rebooting loop
until I get back to the office on tuesday :(.
