When I rebooted (5.14.5-1.gfdb6afd-default, now with nvidia support), everything ran perfectly! No more boot hang, and the messages following "usb: port power management may be unreliable" are back to normal: Sep 17 21:03:44 felicity kernel: usb: port power management may be unreliable Sep 17 21:03:44 felicity kernel: xhci_hcd 0000:01:00.2: xHCI Host Controller Sep 17 21:03:44 felicity kernel: xhci_hcd 0000:01:00.2: new USB bus registered, assigned bus number 3 Sep 17 21:03:44 felicity kernel: xhci_hcd 0000:01:00.2: hcc params 0x0180ff05 hci version 0x110 quirks 0x0000000000000010 So 5.14.2-1-default seems to have a regression to 5.14.1-1-default, while 5.14.5-1.1.gfdb6afd (or earlier, like 5.14.3 or .4 possibly) fixes that. -- You are receiving this mail because: You are the assignee for the bug.
