https://bugzilla.kernel.org/show_bug.cgi?id=216455 Bug ID: 216455 Summary: PCI AER error caused by LTR enablement on amdgpu with LTR disabled on video card PCIe bridge Product: Drivers Version: 2.5 Kernel Version: 5.19.6 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: wielkiegie@xxxxxxxxx Regression: No Created attachment 301753 --> https://bugzilla.kernel.org/attachment.cgi?id=301753&action=edit dmesg with pci=earlydump (v5.19.5 + ltr debug patch) Split off bug 216373 as this is a different issue than what it was initially about. 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=00100000/00000000 > 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=noaer to the kernel. The amdgpu.aspm=0 kernel option makes this issue disappear. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
