    sys/dev/amr          amr.c 
  Log:
  MFC: Chain the bus_dmamap_load() calls when mapping a command with a data
  CCB instead of using BUS_DMA_NOWAIT().  Since bus_dmamap_load() doesn't
  support BUS_DMA_NOWAIT in 4.x, this could result in data corruption if
  sufficient bounce pages weren't available.
