I'm afraid I disagree with this, cat-ing to mtdblock is IMHO absolutely fine. The article you cite is regarding putting normal (i.e non-flash-aware) filesystems onto mtdblock devices, but flash-kernel is using the raw device which is fine and exactly the sort of thing mtdblock is for. > When I have more time, I'd like to try flashcp from mtd-utils and see > if the deadlock still occurs.
