--- Comment #79 from Jesper Schmitz Mouridsen <jsm at FreeBSD.org> ---
I can make CMD25 succeed by adding 

  bus_dmamap_sync(sc->rtsx_data_dma_tag, sc->rtsx_data_dmamap,
BUS_DMASYNC_POSTREAD);
        bus_dmamap_sync(sc->rtsx_data_dma_tag, sc->rtsx_data_dmamap,
BUS_DMASYNC_POSTWRITE);

before the cmd->data->data is memcpy'ed to the data dma buffer.

to the current git source...

*BUT* the follwing/subsequent CMD17 and CMD18 fails..
