I found the offending patch - drm: Stop updating plane->crtc/fb/old_fb on atomic drivers Not sure yet what's going on there and not sure it will fix you issue with amdgpu_vm_cpu_set_ptes page fault after S3 since I haven't observe it here. Still worth a try on your side to revert it and see what happens.
Reverting the commit "drm: Stop updating plane->crtc/fb/old_fb on atomic drivers" for me only changes that after S3 resume, the very picture that was visible before S3 sleep is displayed again - but the kernel crash at "amdgpu_vm_cpu_set_ptes+0x76" still happenes, so the "resumed picture" is as frozen as the system is dead.
