Thunderbolt 3 dock - hotplug / suspend

For a while, there are issues with my tb3 dock.
When I was using my dock first, everything was working fine.

For 2 months or more, there are issues, for example:
    - Logitech wireless keyboard is not working after wakeup-from-suspend sometimes
    - External USB soundcard is not working or produces 1-2s of crackling sound when I play or stop the music after hotplug
    - Connected monitor is not showing up after hotplug
    - Rarely I get kernel panic after hot-unplug
    - Rarely I get kernel panic after hotplug

There are other non-dock related problems, but maybe related:
    - laptop microphone does not work after wakeup-from-suspend sometimes (resuspending solves the issue)
    - After wakeup-from-suspend, the laptop keyboard misses keystrokes but slowly fixes itself.
    - Rarely, after wakeup-from-suspend the laptop reboots itself

I think the hardware is fine because a freshly booted system with the dock is working fine. But after I unplug the tb3 cable, I feel like the current kernel cannot handle this. The same thing happens when I wake up from the suspension.

My setup:

DELL XPS 9500 (intel + nvidia)
    - via DELL tb3 DOCK:
         - headset
         - ethernet
         - HDMI monitor
         - monitor's builtin usb hub:
             - usb mouse
             - usb soundcard
             - logitech unifying reciever


Any ideas on how to make it work again?

Re: Thunderbolt 3 dock - hotplug / suspend

FWIW, I had similar issues with a ThinkPad thunderbolt dock (USB ports not functional after reconnecting).  In my case, I had to reauthorize the thunderbolt device (via boltctl or via GNOME settings > Privacy > Thunderbolt).  After that,  all devices exposed by the dock are functional following a reconnect.
Re : the other issues - those looks firmware related - check for updates with the manufacturer.

I think part of this issue is caused by Nvidia:

Reauthorizing the dock helped somehow.
Thanks

This happens when I run guitarix with pipewire.

What does this treating change event mean? Whatever it does, hid-Logitech drivers cannot handle that.

I guess the "one thunderbolt cable to rule them all" logic is not possible right now.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan
