I have some USB devices connected to that dock: keyboard, speakers (using U= SB audio). The USB subsystem of the dock randomly disconnects with the following trace: [50410.012153] xhci_hcd 0000:09:00.0: xHCI host controller not responding, assume dead [50410.012191] xhci_hcd 0000:09:00.0: HC died; cleaning up [50410.012231] usb 5-4: USB disconnect, device number 2 It disconnects randomly less than one hour after fresh boot or hours later, there is no identifiable pattern. It happens out of the blue while I'm using the machine normally, usually playing audio to the connected speaker via USB audio. Replugging the TB3 cable usually makes USB work again for a while until it disconnects again. A monitor is connected to this dock via DisplayPort and = is unaffected. I noticed that issue starting with Kernel 6.3.4, although it could have happened before. Here's my initial bug report on openSUSE Tumbleweed issue tracker: https://bugzilla.opensuse.org/show_bug.cgi?id=3D1212019 I can provide any additional info required. --=20 You may reply to this email to add a comment.
