Description:

On a ThinkPad X1 with PCIe 4.0 and Thunderbolt 4, after a reboot, USB
Type-C NICs are not detected by the system (not even in BIOS). I am
using a Realtek 0bda:8156 (Lenovo OEM).

And at the same time, logs are flooded by messages like:

[ 30.100211] pcieport 0000:00:1d.0: AER: Uncorrected (Non-Fatal) error received: 0000:00:1d.0
[ 30.100251] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, (Requester ID)

[ 30.100401] xhci_hcd 0000:3e:00.0: AER: can't recover (no error_detected callback)
[ 30.100427] pcieport 0000:00:1d.0: AER: device recovery failed


Additional info:
* package version: linux 6.0.8.arch1-1
* link to upstream bug report: [1]

Steps to reproduce:

1. Cold boot
2. Reboot

The logs issue [1] has been resolved by [2], and the series of patches
has been backported to both Ubuntu [3] and Fedora [4].

And I've identified the commit that solved my NIC issue was [6] after
bisecting it. Backporting [5][6] onto 6.0.8.arch1-1 together with [4]
fixed everything for me.

I wonder if it's ok to backport these to Arch as well? Thank you.

Possibly related to this bug, I discovered that my thunderbolt dock stopped working with either 6.0.8.arch1-1 or 6.0.9.arch1-1 (I didn't reboot between those upgrades).
When booted to the newer kernel mentioned above, my dock-attached keyboard & display (displayport) stopped working. The GNOME settings Thunderbolt tab said "No Thunderbolt Support (newline) Thunderbolt security level could not be determined.".
From the CLI, this is what I saw:
```
❯ sudo boltctl enroll 004c3845-3baa-0801-ffff-ffffffffffff
device with id '004c3845-3baa-0801-ffff-ffffffffffff' already enrolled.

❯ sudo boltctl authorize 004c3845-3baa-0801-ffff-ffffffffffff
Authorization error: wrong device state: disconnected

I downgraded to the following to get my thunderbolt dock working:
```

@hoban You can bisect it if you already knew the change range.

Since v6.1 is out, I'm happy to wait for v6.1.x to land in Core repo. Please feel free to close this ticket (or leave it open for other kernels if you want of cos).
