Sounds like the unstable bits issue reported by Matthieu CASTET . This needs some fixes both in UBI and UBIFS. I tried to describe the issue here: http://git.infradead.org/ubi-2.6.git/blobdiff/a87f29cbbcbd5bd1e4990367cd18967e9bbeacff..a20a51b6d779463b0f1f2fcc81b6fa1225c49e92:/drivers/mtd/ubi/scan.c I am going to work on this as soon as I have some time. But any help is appreciated. -- Best Regards, Artem Bityutskiy (Битюцкий Артём)
