Hello,

with RTnet over Xenomai and Linux 2.4 on PowerPC I realized that Xenomai 
does not distinguish between a normal IRQ enable and an IRQ unmask at 
the end of an ISR (to reenable the IRQ). In the latter case the IRQ 
should be enabled on PowerPC as shown:

    if (rthal_irq_descp(irq)->handler->end != NULL)
  	   rthal_irq_descp(irq)->handler->end(irq);
     else
	   rthal_irq_descp(irq)->handler->enable(irq);

To handle this case properly, we need to different functions, I think.

Wolfgang.
