Please, do the following: 1. inform us about your kernel version; 2. explore http://www.linux-mtd.infradead.org carefully; 3. try the latest MTD snapshot; 4. post to the MTD mailing list - all the MTD people are there. If the last snapshot doesn't help, then: 1. enable MTD debugging and JFFS2 debug level 1 in your .config; 2. post the JFFS2/MTD debugging output; 3. post the output of 'cat /proc/mtd; 4. use the last MTD snapshot.
