ubiattach fails

[Alex Boag-Munroe]

Hey folks, quick question.  I'm playing, or at least trying to play,
with ubifs on my HTC Hero.  Running ubiattach /dev/ubi_ctrl -m 4 gives
the error:

ubiattach: error!: cannot attach mtd4 error 22 (Invalid argument)

I get the following in dmesg:

[  779.384338] UBI: attaching mtd4 to ubi0

I would appreciate any help anyone can provide, thank you.

Lack of planning on your part does not constitute an emergency on mine.
