Dmesg snippet

Title is self explanatory. I've looked into similar reports but my dmesg is different from all of them.

System:
Ryzen 2600
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.
