To quote Bjorn: > The issue you're seeing is an Unsupported Request error logged by a Switch > Downstream Port when it received an LTR message sent by 44:00.0 when the > Switch has LTR disabled: > > pcieport 0000:43:00.0: device [1022:1471] error > status/mask=3D00100000/00000000 > pcieport 0000:43:00.0: [20] UnsupReq (First) > pcieport 0000:43:00.0: AER: TLP Header: 34000000 44000010 00000000 > 84288428 The errors themselves can be masked by providing pci=3Dnoaer to the kernel. The amdgpu.aspm=3D0 kernel option makes this issue disappear. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
