Since every such message happens when the system stalls for like half a
minute I don't think there will be that many until somebody notices
something is amiss. It might be also helpful in diagnosing if other
cards lock up in different way - for me the DMA shutdown is short so I
guess it's the mmc host that is locked up and the DMA engine is fine.
It might look differently on different systems, though.
I understand that adding messages it somewhat controversial so I added
them in separate patch.
