The message file indicates: Transparant bridge - Intel Corp. 82801BA/CA/DB PCI bridge >How do you check interrupt request state? I assume you are referring to the kernel debug stuff that I added? The routine I added simply read the Interrupt Mask Register (IMR), Interrupt Request Register (IRR) and the Interrupt Service Register (ISR). The IMR shows that our IRQ is not masked off. The IRR shows that there is currently no interrupt pending for our IRQ. The ISR shows that we are not currently servicing our IRQ.
