> 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:

* Show the full dmesg and lspci output.
* Does this issue occurs on v6.1.y stable series? If none, can you also check
latest mainline (currently v6.5-rc3)?
