We have seen this problem in the past. We've spoken to Charles Manning
(main Yaffs developer) regarding this problem. He is working to correct
this problem... Any information you could supply Charles would help
him to solve this problem. Yaffs mailing list

BTW I have a kernel and userspace program that will allow you to
recover bad blocks...
