> With FC22 here it seems not necessary.I will try kernel 4 with it. Adrian, For stability, you might want to stick with 3.18 branch for the moment. Don't know whether it was specific to my 4.0.4 build or generically applicable to the rpi-4.0.y tree, and I haven't had time to investigate further, but I was experiencing some random lock-ups with rpi-4.0.y tree, hence the F22 raspberrypi-kernel rpms I made remain in "unstable" repo.
