Comment (by leonardogyn):
the 'NAND flash driver for RouterBoard 4xx series' was updated from 0.1.10
to 0.2.0 on r22863. So let's try before and after that update.
r22862 - NAND flash driver 0.1.10

So, the problem doesnt seem to be related to this NAND flash driver
version change that happened on r22863.
I'll try to look for other possibilities ...
