bus_dma(9)'s capability which honors boundary restrictions of DMA tag for dynamic buffers. However it seems this does not work well and it triggered watchodg timeouts on controller that has the hardware bug. It's not clear whether there is still another hardware bug not mentioned in errata. This should be revisited since this change shall make use of bounce buffers which in turn reduces performance a lot on systems that have more than 4GB memory. Reported by: Michael L.
