            Bug ID: 216497
           Summary: USB connections through thunderbolt dock broken
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.19.9-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 15 Sep 2022
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: USB

dmesg log for thunderbolt dock re-plug

After updating to kernel v5.19.9-arch1-1, usb ports on HP Thunderbolt Dock G2 stopped working. dmesg is getting flooded with the message:

xhci_hcd 0000:30:00.0: Error while assigning device slot ID xhci_hcd 0000:30:00.0: Max number of devices this xHCI host supports is 64. usb usb6-port1: couldn't allocate usb_device

Obviously I don't have 64+ devices connected. Strangely, if I boot with the thunderbolt dock connected, everything works fine. Unplugging and re-plugging the dock again results in unrecognized usb.

I'm attaching the part of dmesg where I unplug and re-plug the thunderbolt dock. Note that all usb devices that are connected are correctly enumerated while unplugging.

Rolling back to previous version of the kernel fixes the issue.

--- Comment #1 from Jonny Mako ([email protected]) --- Ethernet port also does not work. So everything except the DisplayPorts on the dock stopped working with the kernel update.

--- Comment #3 from Mika Westerberg ([email protected]) --- Hi, if the previous version of the kernel works then can you bisect this to a commit that caused the issue?

--- Comment #4 from Christian Kujau ([email protected]) --- When plugging in a Yubico USB-C dongle to this Lenovo T470 (with the latest BIOS 1.71 installed), this happens with 5.19.9-200.fc36.x86_64 today (upgraded from 5.19.8-200.fc36.x86_64 where it worked just fine):

This Yubico thingy should register itself as an input device, but doesn't anymore. Yes, I realize it's a distribution kernel, I'm just adding this here as an additional data point.

--- Comment #5 from Mika Westerberg ([email protected]) --- There are some IOMMU fixes between v5.19.8 and v5.19.9 that might be related as
there are those DMAR faults in the dmesg. It should be pretty fast to bisect
between v5.19.8 and v5.19.9 for the commit causing this.

--- Comment #6 from Jason M. ([email protected]) ---
I am seeing similar except my wireless is broken because the firmware can't load.
https://bugzilla.redhat.com/show_bug.cgi?id=2127753

Among the errors from my dmesg attached over there:

Sep 18 14:28:02 kernel: DMAR: DRHD: handling fault status reg 2
Sep 18 14:28:02 kernel: DMAR: [INTR-REMAP] Request device [01:00.0] fault index

0x8080 [fault reason 0x25] Blocked a compatibility format interrupt request

After running through a bisect reverting just 9516acba29e322202674d18f4dc383879f7813a5 fixes it.

Error while assigning device slot ID. Max number of devices this xHCI host supports is 64.

--- Comment #14 from Marvin Gudel ([email protected]) --- Also confirming this bug.

Fedora kernel-5.19.9-200.fc36.x86_64 on a Dell XPS 13 9370.

Both Thunderbolt capable usb-c ports are affected. The third one works (I belive its not Thunderbolt capable).
