I have no > explanation for that... Well I can't say for 100% sure it wasn't on 6.13.7, but only that on the periods of time I've tested it didn't happen. > So the outcome of testing is that the problem occurs if both the unlucky = hub > and the unlucky webcam are present on the same X670 bus, and disappears if > they are on different X670 buses at the same time? Also on the limited amount of time, that's right, it didn't happen at all during such circumstances (webcam on a separate bus); I didn't test webcam = on same bus, but connected directly on the bus (without the monitor hub); my feeling is that the monitor hub is somehow the issue; I could focus on test= ing that aspect. I also tested with the bootargs, this is the result: ``` bash-5.2# dmesg | grep xhci.*quirks [ 0.537829] xhci_hcd 0000:03:00.2: hcc params 0x0110ffc5 hci version 0x1= 20 quirks 0x0000000200000010 [ 0.539340] xhci_hcd 0000:3b:00.0: hcc params 0x20007fc1 hci version 0x1= 10 quirks 0x0000000200009810 [ 0.595976] xhci_hcd 0000:68:00.0: hcc params 0x0200ef81 hci version 0x1= 10 quirks 0x0000000200000010 [ 0.653978] xhci_hcd 0000:6a:00.0: hcc params 0x0200ef81 hci version 0x1= 10 quirks 0x0000000200000010 [ 0.656224] xhci_hcd 0000:6c:00.3: hcc params 0x0120ffc5 hci version 0x1= 20 quirks 0x0000000200000010 [ 0.657094] xhci_hcd 0000:6c:00.4: hcc params 0x0120ffc5 hci version 0x1= 20 quirks 0x0000000200000010 [ 0.658896] xhci_hcd 0000:6d:00.0: hcc params 0x0110ffc5 hci version 0x1= 20 quirks 0x0000000200000010 ``` --=20 You may reply to this email to add a comment.
