Dying that early is rather odd if you definitely built the Xen and
XenLinux images at the same time. I wonder if it is due to the size of
the initrd (unlikely, as a 16MB initrd isn't *that* big and we often
test with an initrd). Might be worth trying to boot without an initrd
and see if the boot gets further.

If you point me at your Xen and Linux images are, I'll try them out
myself.
