OK, I'm building a test kernel package with the revert in OBS home:tiwai:bsc1133486 repo. A new kernel will be kernel-default-5.0.10-*g8edeab8: http://download.opensuse.org/repositories/home:/tiwai:/bsc1133486/standard/ Michael, once when the new kernel is ready, please give it a try. thanks, Takashi
