First of all, it would be cool if you fixed your e-mail client. I haven't ever seen before anything like this - you put _your_ answer to the ">" quotations, not mine. Here are some guidelines: http://www.infradead.org/~dwmw2/email.html Try enabling UBI extra self-checks as it is suggested here: http://www.linux-mtd.infradead.org/faq/ubi.html#L_how_debug Similarly, try to enable UBIFS extra self-checks. Also, keep UBI/UBIFS debugging enabled. With the debugging and self-checks you may catch something. Also, try to avoid doing 'ubiformat /dev/mtd6 -y', just to make sure it is not ubiformat which screws something. Just do 'flash_eraseall /dev/mtd6'. Also, when you send a bug report, include _all_ UBI/UBIFS output, not only what you see on the console. E.g., use dmesg.
