This is different with previous version. Other people reported problems with that. Sorry about this... This problem should be solved by upstream commit de3ee99b097dd51938276e3af388cd4ad0f2750a "mmc: Delete bounce buffer handling" I just killed off the bounce buffers so they can't hurt anyone anymore.
