Crash on 5.19.0-35 when connecting AMD GPU

[roland]

Bug is present in 5.19.0-35. Booting with 5.19.0-32 works.
I have an AMD 6700XT connected via thunderbolt.

When I connect the egpu there is a hard lock.
I need to do a long press on the power switch to poweroff my laptop.

See the attached boot.log.
It shows the moment I plug in my thunderbol3 device
till the crash.

Searching gave me this bug: #2009136
which also effects AMD gpus.

I have exactly the same problem with my eGPU over thunderbolt:

```
lspci | grep Radeon
3e:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 23 [Radeon RX 6600/6600 XT/6600M] (rev c7)
```

Status changed to 'Confirmed' because the bug affects multiple users.

I tried to go back to kernel 5.19.0-31-generic and everything works well. Then I added proposed-updates to apt which installed kernel 5.19.0-38.39, but it suffers from the same problem as 5.19.0-35
