Using cat /proc/interrupts it will show unknown data of IRQ, but I think it's on kernel bug or Ubuntu won't parse as well, I'm not sure.
Image sample show under IRQ number 49 PCI-MSI edge but I can't recognize what depends on and maybe is a bug?
An image as link shown for above concerns: https://pbs.twimg.com/media/BjouExhCMAAonyR.png
This bug didn't affects on critical errors and not crashes on firmware, drivers, etc...
MOD: Please move from "mousepad" category to kernel or proprietary category.
