I'm guessing this dock uses DP Alt-mode, with both Display port and USB 3 over Type-C. In both resume cases there are some error related to the display: [drm:dm_late_init [amdgpu]] *ERROR* DM_MST: Failed to start MST [drm:amdgpu_device_ip_late_init [amdgpu]] *ERROR* late_init of IP block failed -5 After this all usb devices on usb4 and usb5 buses disconnect (xHCI 0000:06:00.3:) There are no xhci errors in the log, just disconnects, as if Type-C port was muxed away from xHCI. A bit later we see DP Alt mode entry after first resume, and usb devices are enumerated again. [ 136.881649] [drm] DP Alt mode state on HPD: 1 [ 137.153415] [drm] DM_MST: starting TM on aconnector: 00000000018c53ab [i= d: 89] After second resume we don't se this DP Alt mode entry in the log, and usb devices remain disconnected. Not that familiar with Type-C settings, could be AMD specific --=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.=
