  Modified:    sys/i386/isa  gsc.c
  Log:
  Apparently, someone changed the gsc driver to allocate one big buffer
  at device attach time, instead of allocating and freeing buffers as
  necessary. But he or she forgot to remove the line that invalidated
  the buffer when the device is closed. Therefore, after using the
  device for the first time, the buffer was incorrectly invalidated and
  that caused a page fault on the second, and subsequent uses.
