ok. that was just an warning. I re-created anyway the linker.hints and
now that warning is gone.
anyway, here the main issue:
If I keep my RBPI 10 minutes down, no power, all good, time is correctly kept
and displayed.

I will try to keep it off now for +1hr - and then I bet the problems start to show.
