I have built and installbooted a custom first stage bootstrap
(/usr/obj/destdir.amd64/usr/mdec/bootxx_ffsv1) that I can verify
*is* executed at start-up and hangs with any /boot for n9 both
self built and binaries from the official n9.1 release.

This 1st stage bootstrap works fine with all n8 /boot files I
have tried. It really feels that something significant must have
changed with /boot between the n8 branch and the n9 branch
which does not like *my* particular setup...

Below are a few other diagnostics I have tried in case they help
anyone else understand my issue...
