CRC error when mounting UBIFS

Sounds good, I might take a crack at it, I have been looking for some
way to contribute to the linux kernel.

Have I understood the UBI code correctly in that only the
ubi->peb_buf1, ubi->peb_buf2 and ubi->dbg_peb_buf are ever sent to the
mtd->read/write functions? Currently at home and dont really have
anything to test code in.

Does UBIFS ever access the mtd-layer directly?
