So lately I have been having trouble with my ArchLinux installation where sometimes my video card (nVidia GeForce 440 Go) wouldn’t work and sometimes the wireless card would not work. So I decided to take some time to track it down and after spending quite some time I noticed that this was related to IRQ #11 getting disabled. This message appears right after udev is started so I am guessing this has something to do with udev. With the research that I did it seems like this might also be related to ACPI which tries to poll that IRQ but never gets a response (maybe due to some bug?). I have tried disabling ACPI by passing several flags to the kernel command line but the results were random so I took all ACPI related flags out. Anyways my current solution is to just restart when I see that message, I’ll do another post if and when I find a definite solution.
