--- Comment #6 from Daniel daniel@danieltippmann.de --- The situation over here is maybe related:
Hibernating/suspend-to-disk/s4 on my new AMD Carrizo box fails.
Upon hibernate, the system just reboots. No hints in the logs.
Suspend-to-RAM/S3 works fine.
When I disable amdgpu, hibernate & resume work fine.
