Here's the grub line I use for all testing: GRUB_CMDLINE_LINUX_DEFAULT="quiet resume=UUID=b4f71480-8fe3-43c2-99c9-fc3f5687545b libata.atapi_passthru16=0 rd.modules-load=vfio-pci amd_iommu=on iommu=pt amdgpu.modeset=1

Would you try with "iommu=soft", aka disable the hardware one? Maybe try tuning it off entirely.
