Just for kicks, I applied this and ran it on an MSM target (8x50).  It
seems to cause lots of:

  mmc0: Data timeout
  mmc0: Controller has been re-initialized
  ...
  mmc0: Data CRC error

and I can post more if you would find them interesting.  Eventually the
MSM mmc driver derefernces a null pointer in the interrupt code.

It's also possible this is finding problems in our SDCC driver.
