Hi,
There was a regression in 6.2-rc1 that caused amdgpu to not be able to load when IOMMU domain isn't set up properly
It was fixed by these four patches in 6.3.
080920e52148 ("iommu/amd: Fix error handling for pdev_pri_ats_enable()")
f451c7a5a3b8 ("iommu/amd: Skip attach device domain is same as new domain")
996d120b4de2 ("iommu/amd: Improve page fault error reporting")
2cc73c5712f9 ("iommu: Attach device group to old domain in error path")
Can you please bring them to 6.2.y?
