DaveJ, I assume it's too late now, and you don't effectively have any
access to the machine any more, but "hpet=disable" or "nohpet" on the
command line might be worth trying if you ever see that piece of
hardware again.

And for posterity, do you have a dmidecode with motherboard/BIOS
information for the problematic machine? And your configuration?

And finally, and stupidly, is there any chance that you have anything
accessing /dev/hpet?
