Weirdly its with a fresh debootstrap'ed Debian etch (so not "old") Linux
install under FC6; etch under FC5 with an older FC5 2.6.18 kernel doesn't
trigger the nash CPU loop.

I'm running the Debian etch domU with the FC6 Xen kernel (and am putting
the modules into the domU manually so things like xennet and iptables work
for me) with the 2.6.19-1.2911.6.5.fc6xen kernel and a rebuild mkinitrd
(ie, with xenblk.)

I'd be interested in finding out more about what its actually doing
if only to understand things a little more.
