How did 0x16 get into the PCI configuration?
Did you write it there, based on some mistaken notion of what ought to
be there?
Was it put there by BSP auto-configuration?
Physically, how are PCI interrupts routed to the CPU?
Did you enable the full path of the interrupt signal?
When you posted this, did you think you were providing enough detail?
