  Modified:    sys/kern  kern_physio.c
  Log:
  Fix a problem that caused system crashes after physio.  This problem
  was due to non-aligned 64K transfers taking 17 pages.  We currently
  do not support >16 page transfers.  The transfer is unfortunately truncated,
  but since buffers are usually malloced, this is a problem only once in
  a while.  Savecore is a culprit, but tar/cpio usually aren't.  This
  is NOT the final fix (which is likely a bouncing scheme), but will at
  least keep the system from crashing.
