Log Message:
When a read DMA transfer is interrupted by a disconnect on the IOASIC SCSI
and the buffer is not 8-byte aligned, it leaves a partial transfer in the
SDRx registers.  This could cause data corruption in dump(8) because the
read-ahead buffers are allocated on a non-aligned address.  When the read
DMA transfer is interrupted and the current DMA position is not aligned,
call the dma_end() routine to flush the SDRx register contents to the
buffer.
