https://bugzilla.kernel.org/show_bug.cgi?id=217715 Bug ID: 217715 Summary: USB from Thunderbolt 2 dock disconnects (xHCI host not responding) Product: Drivers Version: 2.5 Hardware: All OS: Linux Status: NEW Severity: normal Priority: P3 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: youp1one1@xxxxxxxxx Regression: No System details: Operating System: openSUSE Tumbleweed Kernel: Linux 6.4.4-1-default Architecture: x86-64 Hardware Vendor: Lenovo Hardware Model: ThinkPad P72 Firmware Version: N2CET65W (1.48 ) Firmware Date: Mon 2022-08-01 I have an old Elgato Thunderbolt 2 dock connected to my laptop's Thunderbolt 3 port via the Apple TB2->TB3 adapter (https://www.apple.com/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter). I have some USB devices connected to that dock: keyboard, speakers (using USB 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=1212019 I can provide any additional info required. -- You may reply to this email to add a comment.
