starting in nb->notifier_call:
tick_notify()
tick_check_new_device()
tick_setup_device()
tick_setup_periodic():
it seems to enternally loop in here:
123 for (;;) {
124 if (!clockevents_program_event(dev, next, ktime_get()))
125 return;
126 next = ktime_add(next, tick_period);
127 }
I think it's waiting for a timer irq which never happens. The code in
cevt-r4k.c assigns IRQ 7 as the timer irq which is a GPIO according to
the manual. Actually, there is no real requestable() timer irq mentioned
in the manual (RTC and TOY aside).
Thanks!
