I've had some kind of hardware failure on a laptop that requires me to boot with the kernel parameter acpi=noirq. This turns of my wifi. No good. Is there a way to turn it back on after boot? I tried a bunch of the other irq related options (including disabling all of the ports but one, and then another one), and noirq seems to be the only parameter I can use to boot (besides acpi=off). I'm trying to figure out which piece of a hardware has failed so I can replace it, but I'm not sure how.
