One other thing to note here, the proper operation of hot plug dictates that if you boot your laptop with no adapter in the slot, you must first load the driver in order for the new adapter interrupt to be captured. So, if you insert a card without the driver loaded, it will not be enumerated by PCI until you remove it and the reinsert it. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
