I ran into something similar to what you're reporting here while looking at
another issue this evening on a newly updated development machine.

I was hitting an oops at unload when dma_unmap_single was called instead
of pci_unmap_single, where as you were hitting it when the dma buffer is
mapped, but it is probably very similar.

Could you try a version of the trunk that includes this commit:
