The /boot code which works was installed at 07:36 UTC July 9th. So,
every change to the boot code since then is a culprit.

Example: 9c1c02093b90ae49745a174eb26ea85dd1990eec change to support.4th.
It just so happens that I had a nextboot.conf in the "bad" /boot at the
time that the hang occurred.  This is the only potential candidate I
can see.

So I'll try overwriting support.4th with the known-good version and
see what happens.  But probably not until tomorrow my time.
