UBIFS failure & stable page writes

[Prins Anton (ST-CO/ENG1.1)]

Ok clear!

Regarding mount debug: I suppose I only will see this on the 'first' boot after the problem is in the persistence storage?
(Up to now I'm not able to signal the point-of-failure... I'm only looking to an (possibly) after recovery situation).

Or makes this sense to do this mount debug on the existing failing device?

FYI: 
- with 100 devices power cycling every 5 minutes for a weekend we DON'T see a problem.
- with 100 devices powered on for a weekend and after that give a single power-cycle shows maybe 1 or 2 failing devices (but sometimes '0').

So a main problem in analyzing is the 'moment of failure' and 'reproduction (rate)'.

That checks for missing orphans but the problem is the opposite: the
presence of orphans that should not be there.
