In that case, try to install the old openSUSE-13.2 kernel on top of Leap system. It should still work in general, and in that way, we can see whether it's a kernel regression. If 4.1.8 kernel still doesn't work, try the kernels in OBS Kernel:stable and Kernel:HEAD repos. They contain 4.2.x and 4.3-rc kernels, respectively. If these upstream kernels have the issue, we should report it to upstream.
