Er, do you mean your Flash block is exactly 20000 bytes?

One obvious thing I may suggest to exclude driver problems is to use
mtdram device. It emulates NOR flash in RAM. (mtd/drivers/mtdram.c). If
your problem won't go when you've utilized mtdram, the problem is most
probably in JFFS2.

Another good experiment is just to format your flash (flash_eraseall -j)
and mount it (empty). Then to try to play with symlinks there (touch
file; ln -s link file; and like). This will exclude the possibility of
mistakes when you create and flash your image.

Another things I may suggest are:

1. Try my recent patch: http://lists.infradead.org/pipermail/linux-
mtd/2005-February/011936.html

2. If you post next time, please provide the JFFS2 level 1 debug output.

3. Just in case, provide cat /proc/mtd output.
