I really suspect your nand driver is broken. Sorry, I have no idea what
is going wrong here, but the ubi code is derived from the kernel, I
don't expect these kinds of bugs here.

You should first make sure that you have a working kernel. You have ubi
errors there aswell, right? I would expect that the kernel driver and
ubi layer is in better shape, also the audience will be bigger if
something is going wrong in the kernel.
