New: USB from Thunderbolt 2 dock disconnects (xHCI host not responding)

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: [email protected]
          Reporter: [email protected]
        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:

I can provide any additional info required.

* 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)?

Thank you for your response.

I attached both files. Note that I only have USB audio attached to the dock for these files. The end of dmesg shows me replugging the TB3 cable.

I will test later with v6.5-rc3 and report.

I've been testing with v6.5-rc3 and it has been promising, with no disconnections during several hours.

For the time being, I had to revert to the distro's current kernel for other reasons (some third party modules not being compiled for 6.5) but I will be able to definitely tell is v6.5 fixes this issue when Tumbleweed is updated to it, I suppose in a few weeks.

I have not seen this issue happening since Kernel 6.5.6, so closing it.
