Hello Paul! Thank you for pointing this out. I think we are missing a patch here which was actually sent for up-stream but did not make through as I don't see it on my latest master branch. http://patchwork.kernel.org/patch/49514/ Can you please apply this and see if it helps, I don't have any 2430SDP platform to test.
