I got a clue from YAFFS mailing list, this is a known issue on 2.6.18 kernels.
It is caused by the MTD layer rework and corresponding yaffs-mtd layer
modifications. Namely, an additional translation had to be implemented
for OOB area for 512b page chips.

But I'm not sure what should be changed to fix this issue. Now I'm
using the newest yaffs, should I upgrade mtd in the kernel to the
newest version? ( The kernel I'm using is 2.6.18).
