Title is self explanatory. I've looked into similar reports but my dmesg is different from all of them.
Asus PRIME x470 PRO
16GB of RAM at JEDEC speeds
Reference navi 5700
4K freesync enabled LG display
Arch Linux with lcarlier's mesa-git+llvm-git+xf86-video-amdgpu-git and amd's staging kernel.
Upon resume I captured this via SSH. System still "works", without screen. Touching GPU stuff like the debug reset just makes it worse and/or completely freezes the thing.
