Does it exist in the tarball that emrootfs made? i.e. is the original
filesystem wrong, or is it something to do with the conversion to
jffs2 image and/or copying on to the flash?

Clearly your jffs2 filesystem is not at all happy. I don't use jffs2
so I don;t knwo the runes offhand, but I suggest there is something
wrong with your above runes for filesystem image generation, or
more likely you need to use the nand utils to write it to the flash, not
cat (in order that the OOB CRC info is corrrectly written - I assume
you are writing to NAND, not NOR?)

That is likely to be a kernel problem.
