    sys/dev/fdc          fdc.c 
  Log:
  The wakeup() line from the rev. 1.319 is wrong and reintroduces
  a panic race on module unload. The wakeup() is internal to
  kproc_exit/kthread_exit. The correct fix is to fix the msleep() in
  detach to sleep on fdc->fdc_thread instead of &fdc->fdc_thread.
