Sorry, I had FP off. Now, when pressing any key (irq 79) and then attaching gdb it says

handle_IRQ_event (irq=79, action=0x0) at kernel/irq/handle.c:427
427		local_irq_disable();
(gdb) bt
#0  handle_IRQ_event (irq=79, action=0x0) at kernel/irq/handle.c:427

I'm curious why it uses "handle_level_irq" although they should be configured as edge-triggered. I'll have a look.
