It should wait in parport_wait_event. Could you add some prints there?
Interesting would be the timeout values. If everything goes ok,
parport_wait_event should continue with down_interrutible, after
parport_ieee1284_wakeup was called. The question is now whether we get
to down_interruptable at all or if something else interrupts it before
up() is called in parport_ieee1284_wakeup (e.g. a timeout).
