Kernel log

1. Please describe the problem:
Using P1G3 connected to TBT dock and when you unplug/plug the DisplayPort or HDMI connection the nouveau driver times out and the external display can't be made to work.

2. What is the Version-Release number of the kernel: 5.8.17

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
I don't think it worked previously.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Yes:
Reboot, with DP in and HDMI out
Unplug the Display Port adapter
Plug in the HDMI (or DP again) and confirm it's broken

I'll attach a video of it bring reproduced by the PA team, as it helped me confirm by following the same sequence

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
Don't know.

6. Are you running any modules that not shipped with directly Fedora's kernel?:
No

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.
