This old issue needs a CVE name. "[PATCH] Input: atkbd - throttle LED switching On some boxes keyboard controllers are too slow to withstand continuous flow of requests to turn keyboard LEDs on and off and start losing some keypresses or even all of them. Delay executing of LED switching request if we had another one within 50 ms thus easing load on the controller."
