At least for me I found a reproducible workaround for the resume bug. I found it more or less with try and error.
I added the option "EnablePageFlip" to the configuration file "/usr/share/X11/xorg.conf.d/10-amdgpu.conf" like this:
Section "OutputClass" Identifier "AMDgpu" MatchDriver "amdgpu" Driver "amdgpu" Option "EnablePageFlip" "off" EndSection
and restarted. With this option set my computer always return from suspend. I do not really know about the impact of "EnablePageFlip" but I do not feel any significant degradation of video performance.
Maybe this will help to catch the annoying bug.
