This happens with the device tree from the kernel, but not the device
tree from git://xenbits.xen.org/people/dvrabel/device-trees.git
I happens when either the /chosen node is missing or bootargs is
missing. This is easy to fix. However, the kernel fails to boot
because it doesn't get the device tree which is odd.
I'll look into it some more.
