Reverting the commit "drm: Stop updating plane->crtc/fb/old_fb on a=
tomic
drivers" for me only changes that after S3 resume, the very picture th=
at was
visible before S3 sleep is displayed again - but the kernel crash at
"amdgpu_vm_cpu_set_ptes+0x76" still happenes, so the "resume=
d picture" is as
frozen as the system is dead.
