Does it work if you disable SME? amdgpu doesn't actually work yet with SME enabled anyway. It's odd that SWIOTLB fails allocating 256KB this early, but it might be due to SME creating pressure on SWIOTLB. Yep, works fine with `mem_encrypt=off amd_iommu=off` *** Bug 106496 has been marked as a duplicate of this bug. *** -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
