Yes, this bug also affects me. I upgrade from Kubuntu 19.04 with 5.0 kernel to 19.10 with 5.3 kernel, and got described behaviour:
1. On 5.0 there is no problems (if I boot it in 19.10) 2. on 5.3 with default settings - there is a black screen after try to resume. 3. If I choose XRender with 5.3 in plasma settings - no problems. current kernel 5.3.0-19-generic #20-Ubuntu SMP Fri Oct 18 09:04:39 I have no traces of oops in log, journalctl -b -1 -k show only kernel: PM: suspend entry (deep) string before resume/hang at black screen. current driver xserver-xorg-video-amdgpu 19.0.1-1ubuntu1 amd64 xorg log [ 10.353] (II) AMDGPU(0): glamor X acceleration enabled on AMD RAVEN (DRM 3.33.0, 5.3.0-19-generic, LLVM 9.0.0) [ 10.353] (II) AMDGPU(0): glamor detected, initialising EGL layer.
