Thanks for your detailed explanation and feedback, I am a bit confused about the
#4 you mentioned here ->

> 4) Affinity of the demultiplex interrupt

Are you saying there is a chance to queue this demultiplexing IRQ event
to the current running CPU ?
would it fall into the first if clause ?

> if (desc->target_cpu == smp_processor_id()) {
> handle_irq_desc(desc);

And that's really an approach worth to try, I will work on it.

Thanks
