This error should not happen normally. Or this controller has some 
problems with DMA mode (it's PCI class reports that DMA is not 
supported, but as soon as we have some reports that it does working it 
is forcefully used) or it is some problem with driver. To get some info 
about what is happening actually, uncomment two fragments in driver. This:

/*      printf("%s cmd op %u arg %u flags %u data %ju\n", __func__, 

             req->cmd->opcode, req->cmd->arg, req->cmd->flags, 

             (req->cmd->data)?req->cmd->data->len:0); */ 


and this:

/* 

                 slot_printf(slot, "got interrupt %x\n", intmask);
*/ 


Enable verbose messages, and send me what you will get.
