If this is the case, how can I determine the driver responsible for this bug? $ grep 16: /proc/interrupts should give you an idea of what device or devices are on IRQ 16. And yes, my understanding of IRQs is that a device raises an interrupt to let the computer know that something it ready (data, an error, etc) the appropriate driver should then notice that (or perhaps be notified of it) and service the interrupt. If no-one responds to the kernel saying There's something happening on IRQ 16, then you get the message above.
