https://bugzilla.kernel.org/show_bug.cgi?id=210301 --- Comment #4 from ramast (me@xxxxxxxxx) --- After more log review it seems I had two problems: One related to have two graphics card and that's the one resulting in the "amdgpu_ib_ring_tests" error https://pastebin.com/Eu7PF3en Then after disabling the Dedicated graphics card, I got the error in my previous comment. After removing iommu_v2 I am finally error free. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
