Hmm, that's ugly. Since these errors involve lots of bits, this is
probably not related to the ECC. Maybe there's some disagreement
about block sizes. Strange, though, that one part of JFFS2 would
disagree with another part (both in-kernel).

As far as NAND geometry is concerned, it should be fine.
