Since nobody else has responded, I thought I would try to clue you in a little about IRQs. I'm afraid I cant help you with your problem though.
IRQ stands for interrupt. This is a method for handling data flow to or from a hardware device. (An alternative is DMA -- direct memory access -- where a device can write or read data directly to/from memory.) With interrupts, when a device has data ready, or is ready to accept more data, it asserts a hardware line called an interrupt -- so named because that is what it does. Within some constraints, it causes the processor to interrupt what it is doing and service the hardware. This way the software does not have to keep polling the hardware: are you ready yet? are you ready yet? are you ready yet?
In your case, the number 11 simply represents one of a number of interrupt lines that can interrupt the processor.
