Yeah this is the *working* boot. I can't easily get logs of the
non-working one because, well, no writable filesystems and most of the
interesting stuff scrolls straight off the screen anyway. (It's mostly
for comparison with the non-working boot once I manage to capture that.
Somehow. A high-speed camera on video mode and hand-transcribing? Uggh.)
