I tried booting my 4460 Panda - which is the closest thing to 4430SDP 
that I've got - on next-20141217, but I could not get it to the point 
where the omap-abe-twl6040 probed. It probably is the problem you are 
talking about as the hang does not happen if I disable ASoC ABE all 
together, right?

I'll take a deeper look at it tomorrow, as Peter is not working ATM.
