UBIFS failure & stable page writes

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

Creation is of the problem is not that easy, but once you boot and this happens it is reproducible every boot.
Even if I copy the image (nanddump) to another device the failure moves with the image.

Met vriendelijke groeten | Best Regards,

I think your error was about the root inode:

"ubifs_iget: failed to read inode 1, error -2"

which is the inode of the root directory. Just like everything else, it
is stored in the index tree.

Of course the root inode is required to access the file-system. For some
reason it cannot be found. Probably if you enable all debug messages -
it may be useful.

Is this problem reproducible?
