But the problem is that the kernel calls do_level_irq() which is in
arch/arm/kernel/irq.c Could it mean that it was a spurious interrupt
but was not recognized as such? Unfortunately, irq.c does not have
option similar to noirqdebug so the only thing I could do is to comment
that section of code out.
