So this seem inexplicable :

Actually the battery was 100% full ( double checked before and immediately
after regaining access, so this is ruled out.

NOR boot can theoretically be affected by some things like inherited PMU

 That's how I updated, too , so then I really wonder what had happened -
and how to get back in a sane state should this happen again!
