That would seem to correspond to the 21% usage you noted assuming yaffs is
reporting % of total size.
The question is whether these retired blocks are really fautly or whether some
bug or electrical defect has caused them to be marked as bad.
How old is this board and what root fs is it running? Is it still on factory TS
linux and kernel?
How much use did it get before you set up everything is tmpfs?
