I assume there were no messages containing YAFFS ReadChunk with dummy ECC 
info.
That means, YAFFS supplies always a pointer to yaffs_oobinfo structure. 
Do the "I'ts not recommended ...." messages follow up the above message, or 
show they up elsewhere ? That means, are they really related to accessing the 
YAFFS partitions ? Please provide a short debug output, where I can see the 
context of those "It's not recommended ..." messages.

Are there any other functions accessing the flash device ? 

You use 2 partitions out of 5 for YAFFS. What are the other partitions for?
