What sort of death?  Please describe all sympthoms of the patient.

It is consistent with another bug report on IP27.

The function tick_notify has been installed as notifier, so that is what
I think nb->notifier_call() should be pointing at.  So it should be
called like this:

  tick_notify(&tick_notifier, CLOCK_EVT_NOTIFY_ADD, dev)

So things are likely going wrong somewhere in there.
