Can you try apply this patch: https://lore.kernel.org/all/20210920163922.313113287@linuxfoundation.org/?
linux kernel 5.15rc1 is good, suspend to disk resume success. linux kernel 5.15rc2 is bad, suspend to disk failed. revert "drm/amdgpu: move iommu_resume before ip init/resume" can suspend to disk resume success.
linux kernel 5.15rc2 has "drm/amdkfd: separate kfd_iommu_resume from kfd_resume", why you suggest me apply the patch
