Would it be possible for you to add the atomic counter underflow check
to 2.6.21-rc3 and see if the problem still occurs? If it doesn't,
that's a good indication the USB stack isn't guilty -- the bus
registration code hasn't changed for several kernel releases.
Yes.
I can confirm, that this issue went upstream and is currently present there.
