OK. it's probably a compiler bug, I'm not sure how to fix this.
Changing compile optimisation options usually works around this kind of
problem.

It's the device where the kernel will write a core dump if it panics.
It's usually the swap partition. This will be changed when /etc/fstab
is read later, when the swap device is activated.

kernel core dump doesn't work for Xen kernel at this time.

You should be able to use
root=sd0a
in /boot.cfg
