Re: [Xenomai] RaspberryPi kernel 3.8 issue

[Gregory Dymarek <gregd72002@gmail.com>]

Thank you for such quick response!

Actually yes, this is a warning. Sorry.

That's the content:
irqreturn_t handle_irq_event_percpu(struct irq_desc *desc, struct irqaction
*action)
...
 if (WARN_ONCE(!irqs_disabled(),"irq %u handler %pF enabled interrupts\n",
irq, action->handler))
      local_irq_disable();


Should the IRQs be 'not disabled' at the first place?

When running unpatched kernel this is not the case.
