UBIFS failure & stable page writes

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

First I will check when, how often and which nodes are written to the orphan area.
I guess they (0 & 1) must be listed in the orphan area to get this recovery messages...

It means I currently look to a resulting situation (after power-cycle) and I suppose not the problem itself.

How can I determine the location of the orphan area?

Met vriendelijke groeten | Best Regards,

These are very strange messages. Inode 0 should not exist. Inode 1
should be impossible to ever delete. Smells like some kind of memory
corruption. Can you share your image? Or at least the orphan areas of
the image? We do not have much time, but would probably take a look.

Would also be useful to have the fs/ubifs/* and drivers/mtd/ubi/* of
yours.
