I tried with Linux 4.14.0-041400rc3-generic, the problem is still there unfortunately.
I attached a piece of /var/log/kern.log when I did the suspend/resume. Interesting parts: Oct 3 21:03:28 c18 kernel: [ 62.519787] [drm:amdgpu_vce_ring_test_ring [amdgpu]] *ERROR* amdgpu: ring 14 test failed Oct 3 21:03:28 c18 kernel: [ 62.519795] [drm:amdgpu_resume_phase2 [amdgpu]] *ERROR* resume of IP block <vce_v3_0> failed -110 Oct 3 21:03:28 c18 kernel: [ 62.519803] [drm:amdgpu_device_resume [amdgpu]] *ERROR* amdgpu_resume failed (-110).

I wonder who should be contacted to get more help about this hardware/driver. ** Attachment added: "kern.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720622/+attachment/4961736/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720622 Title: Cannot wake-up from sleep mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720622/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
