There is no formal bug, though there are several related possibilities. Given the LL distro and the fact that the issue is somewhat hardware specific I would say that it is a recurring systemd write issue with backlight on some hardware systems. There is probably no wide range solution. Those of you that have this issue will have to work within hardware specifics. I tried to find a comprehensive issue related page to reference from. I expect some experimentation will be necessary to solve the issue, but as I related it is definitely hardware specific, and you will probably need to boot to bash. I can't be of much service to test because all 4 of my desktops (Dells and HPs) and my two laptops (Dell and Toshiba) do not have this problem.
