I saw huge amount of e-mails like this, but for JFFS2. In most of the
cases the reporters had one of:
1. flash problems - the driver or HW was broken
2. flashed images incorrectly

Please, check these 2 cases. To check the first ones, please use
mtd-tests git repository:
git://git.infradead.org/users/dedekind/mtd-tests-2.6.git
(http://git.infradead.org/users/dedekind/mtd-tests-2.6.git)

The tests are not in main-line so far, so you have to take the 8 patches
from the above git tree, apply them to your tree, enable the tests and
compile.

The tests are kernel modules. Please, make sure they work without errors
for you. Note, be careful with the torture test - either do not run it
or realize what it is doing before running.

Vs. the second possible issue - just describe how you flash your UBIFS
image to your "data" partition, if you do this at all.
