I have some additional info (this laptop is <1wk old, I'm still discovering behaviour). If I boot the laptop with the dock plugged in, boltctl sees the dock and cable as connected but the attached ports and peripherals are not visible - except for the external monitor, which does work. If I un-plug then re-plug the dock, the port discovery messages show in kern.log and all the peripherals/usb-hubs/etc. appear. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922336 Title: ACPI errors and USB reset loop when hot-plugging a Titan Ridge laptop into a dock (9500, TB16) To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1922336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello, I have this problem too - XPS 9500, TB16. No problems using this dock with previous laptop (XPS 9550). Some extra information that I didn't see mentioned is that USB storage connected to the dock (USB-A keyfob, USB-C Samsung T5) seem to work OK, and dock ethernet seems OK. For me, anyway. I also have a DVD-ROM plugged in that seems OK (haven't read a disc, but I can 'eject dvd' and the tray opens). For me the USB mouse is the problem - it doesn't work. Every 1 min it reconnects, works for <1 second, then stops working. Have tried front USB3, rear USB2 & USB3 ports, all have same symptoms. I'm on kernel 5.11, have updated TB16 firmware to 1.0.4. I dual-boot this system with Windows, with latest drivers/FW installed. BIOS is 1.7.1. HOpe this is helpful.

@koba, with everything removed there is no ACPI error on plugging the dock back in. However, if I start plugging external devices back into the dock after it has registered with the system, the USB reset loop behaviour is still exactly the same as in the original post. In the attached log, I removed the dock (with nothing attached to it) at 22:00:11, plugged it back in at 22:00:23 with nothing attached to it, started attaching external devices to it at 22:01:33. ** Attachment added: "kern-nousb-nomonitor.log" https://bugs.launchpad.net/ubuntu/+source/linux-meta-oem-5.6/+bug/1922336/+attachment/5495605/+files/kern-nousb-nomonitor.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922336 Title: ACPI errors and USB reset loop when hot-plugging a Titan Ridge laptop into a dock (9500, TB16) To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1922336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I should add that on 5.12 there is no USB reset loop observed in my original post; USB devices attached to the dock just don't work at all when re-plugging in the dock, even sporadically. After re-plugging in the dock, the built-in laptop keyboard works, but calling anything that relies on sudo/root, even just "sudo dmesg" or "reboot" hangs indefinitely. The terminal keeps blinking, so it's not a complete hard freeze. Removing the dock again does not make it recover. Hard-reset is the only thing that is left at that point to get the system operational again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922336 Title: ACPI errors and USB reset loop when hot-plugging a Titan Ridge laptop into a dock (9500, TB16) To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1922336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1922336] Re: ACPI errors and USB reset loop when hot-plugging a Titan Ridge laptop into a dock (9500, TB16)
apport information ** Tags added: apport-collected focal ** Description changed: I've recently upgraded my workhorse from XPS 9560 (2016) to a newer generation XPS 9500 (2020) and ran into several things that feel like regressions, but are probably related to hardware changes. This is one of them. tl;dr: When using XPS 9500 with a TB16 dock, hot-plugging the dock causes ACPI errors in dmesg and some kind of reset loop with USB peripherals connected via the dock. details: USB peripherals keep reconnecting according to dmesg, but in practice they barely ever finish registering with the system before disappearing again. Maybe 1 out of 40 USB keyboard presses registers while this is happening. At this point my choices are to either reboot with the dock connected or work without the dock and consequently without any peripherals on my desk. Booting with an open lid and the dock connected works fine until I re-plug the dock. Notably, it hot-plugs fine every time when using XPS 9560 or Precision 5520 in the same setup which I have been using for ages and which had similar problems until around kernel 4.13. Since it was fine with 9560, 5520 and a friend with a 9570 has no issues either, my gut feeling is that this is due to the upgrade from Alpine Ridge to a Titan Ridge Thunderbolt controller that happened in this generation - something wrong with the driver, or the firmware may have missed some of the "lessons learned" in Alpine Ridge and caused this regression. That would also make it applicable to 9300, which has a "developer edition" option under Project Sputnik. I have attempted 5.8 Ubuntu generic, 5.6 OEM (-20.04) and 5.10 OEM (-20.04b and -20.04-edge) kernels on the 9500 with same results. I have attempted rebinding the XHCI controller after reconnecting the dock. I have attempted disabling USB autosuspend and ASPM via a GRUB kernel parameter. I have attempted playing with BIOS settings: wake on dell usb-c docks, disable early sign of life for both checkboxes, disabling SGX and SMM, checking all 3 boxes for Thunderbolt and switching off Thunderbolt security. None of these make a noticeable difference.
