Hi Meelis, Fixes for the worst of these issues are in v4.18-rc1. I think there are still cases where we will complain about conflicts. Some of these look like they result from OF/DT descriptions that contain conflicts, and they may not cause a problem other than the message itself. If you have a chance to try out v4.18-rc1 or later and if you still see things broken, please let me know and include the dmesg log. Bjorn
