> I have upgraded a Lenovo S540 from Fedora F23 (kernel-4.5.7-200.fc23.x86_64)
> to F24 (kernel-4.6.3-300.fc24.x86_24) and the display started flickering at
> the edges. The next kernel-4.8.0.0.rc1.git0.1.fc25.x86_64 flickered and
> produced a loop,while the display changed the brightness. Touching the mouse
> stopped the failure. Then it started again.
> Kernel-4.8.0.0.rc3.git0.1.fc25.x86_64 doesn't flicker any more, but the ugly
> loop with the changing brightness is still there during the boot process.
> When I turn off the computer the display turns into a very bright white.
