The interrupt for the harddisk and the network chip are GPIO interrupts.

I added a kernel timer to the a driver of me witch does a printk every
10 seconds. The printk shows up so I think that Linux still gets its
timer interrupts.

I also added an interrupt handler on a button which is connected to GPIO
pin. The interrupt handler should print something when it is executed.
When I push the button a couple of times nothing happens. So GPIO
interrupts doesn't seems to work.

Sorry, my apologies.
