The link engages via t= he SMU path: "amdgpu 0000:c2:00.0: [drm] USB controller 0000:c2:00.4 D0 power state depends on 0000:c2:00.0". The v4 patch fixes the controller death on = this hardware. On the full-system hang: after arming hung-task/soft/hardlockup panic (dump= to efi-pstore), I got 140 consecutive hang-free cycles on v4 with the rear por= ts empty. Given I previously saw hangs within 1-13 cycles (twice on kernels without the fix, once on v4 with USB devices attached to the affected controller), it may be a rarer expression of the same resume race rather th= an an independent bug. If it ever fires again the panic trace will be preserved and I will attach it. --=20 You may reply to this email to add a comment.
