So now I have more questions:
1. What got broken between 313109 and 313441? There has to be more than
one problem for the Pi3 because -HEAD not only blows up in
/boot/loader.efi but *also* the running system that is produced (since
if I replace /boot/loader.efi with a working copy I wind up with a panic
before the system finishes starting up, so the damage isn't limited to
sys/boot/efi).
2. I assume the patch on the previous is responsible for silencing the
lock-order-reversal complaint in the uploaded image. Maybe. Probably,
actually, since I get a complaint after signing in even after the first
boot (where growfs runs) but don't on the pre-built image.
There isn't much that's been changed in the loader that looks like it
could bear on this -- the interesting change might be in r313442
although I don't see why a test for NULL (which is the only change in
there) would result in the problem. I'm going to start stepping forward
in the loader until I get the crash, and take it from there unless one
of the committers knows what went wrong.
