  Modified:    sys/i386/isa  aha1542.c
  Log:
  Add the attempted DMA address to the 'DMA beyond end of ISA' message so that
  we can see if it's a small distance beyond the end, or way out. This may
  give some clues as to whether it is being caused by something coalescing
  the transfers in spite of the bounce buffers, or simply because of buffer
  corruption.  (The BT driver seems to occasionally get hit by from this too,
  except that it does not trap the transfer, and the system panics later
  with vm_bounce_page_free.)  This "event" usually happens to me during a
  savecore (on the rare occasion that a kernel coredump is actually taken
  after a crash - the lack of kernel core dumps is another problem...).
