Hi @kolAflash,

 I don't have issue with your .config. on ubuntu 20.04

>From source code, it should be fine.

$ grep -rn  "kgd2kfd_resume_iommu"  drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h
309:int kgd2kfd_resume_iommu(struct kfd_dev *kfd);

$ grep -rn  "amdgpu_amdkfd.h\|kgd2kfd_resume_iommu" 
drivers/gpu/drm/amd/amdkfd/kfd_device.c
31:#include "amdgpu_amdkfd.h"
604:    kfd->pci_atomic_requested = amdgpu_amdkfd_have_atomics_support(kgd);

940:int kgd2kfd_resume_iommu(struct kfd_dev *kfd)


Looks we are using different 5.10, should we use 5.10 stable for adding this
backport patches?.

Best Regards!
