Well, the device does report 99% free according to "df" after eraseall.
Further, a "mkyaffs" on the device does not state that there is 
thousands of bad blocks - just the factory ones, so I think eraseall 
does it correct?
Moreover, I tried it on a new NAND device never before being used for 
YAFFS, and the same occured (with my new kernel without YAFFS_ECC)...

You still think I should try without bad block checking?
