Hi Arnd,
First bad commit (maybe != root cause):

As far as I can tell, this is a bug with the m68kmmu architecture, not with my driver: The CONFIG_ISA_DMA_API option is provided for coldfire, which implements it, but dragonball also sets the option as a side-effect, without actually implementing the interfaces. The patch below should fix it.
