We tested all of the changes with the setup in tools/boot/rootgen.sh, it
will be interesting to figure out what went wrong with your setup, and
add it as a test case to prevent this in the future.

The recent changes are:

r335245 (reading the size of the disk)
r335254 (reading past the end of the disk)
r335276 (enable the serial console sooner so the password prompt can be
used over serial)

There is also one outstanding fix: https://reviews.freebsd.org/D15847
