To make sure that the problem is in my patch: could you try the latest kernel in OBS Kernel:stable repo? http://download.opensuse.org/repositories/Kernel:/stable/standard/x86_64/kernel-default-4.16.7-2.1.g938738d.x86_64.rpm It's the base git commit my fixes are applied. This doesn't contain the revert, and BT must work with it.
