Interesting. This time it booted all the way to GPE. But, hid2hci
faulted and the kernel trapped on it. Nothing strange at all about
that binary, and the same one works fine on the OABI kernel.

Well, bottom line I don't think I'm doing anything wrong, but I can
say leaving out the OABI option always gives me trouble. Any light
you can shine would be great!
