            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@kernel-bugs.kernel.org
          Reporter: youp1one1@gmail.com
        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.

* 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.
