With boot -1, the boot completes.

Yes, so does mine.  And it isn't unlikely that mine stops
on the cpu1 line rather than the cpu0 line too, on a video
console it is on the screen for only a tiny bit of time and
I had to watch it boot a half dozen times before I managed
to get my eyes to see anything at all.

Please try this one:

This is a workaround, until I work out this problem with a cleaner solution.
