Same thing as Rupert. Here is my situation, having uninstalled amd's
drivers per their instructions, and also removed amd repos. I guess I
have to reinstall Windo- I mean Ubuntu.

Title:
6.8.0-44 breaks amdgpu-dkms 6.8.5
Status in linux package in Ubuntu:
Won't Fix
Bug description:
Ubuntu 24.04.1
6.8.0-44 causes compile failure of amdgpu-dkms (6.8.5 from AMD
partner)
```
linux-image-generic 6.8.0-44.44
amd64 Generic Linux kernel image
amdgpu-dkms 1:6.8.5.60200-2009582.24.04 amdgpu driver
in DKMS format.
noble/main
amdgpu-dkms-firmware 1:6.8.5.60200-2009582.24.04 firmware blobs
used by amdgpu driver in DKMS format
noble/main
```
The 6.8.0-44 kernel includes :
* Noble update: upstream stable patchset 2024-07-25 (LP: #2074091)
- drm/mst: Fix NULL pointer dereference at
drm_dp_add_payload_part2 <---- This is the one
This one causes a compile failure in amdgpu-dkms 6.8.5 , detected
from rocm6.2 users and initially reported there, but i believe it
should be fixed in Ubuntu who backported the fix causing the bug.
https://github.com/ROCm/ROCm/issues/3701
https://github.com/ROCm/ROCm/issues/3701#issuecomment-2351247361
contains a trivial patch on the amdgpu-dkms side, but the problem is
introduced by a patch on the kernel ubuntu-6.8.
this is very annoying, and proposed workaround on github Amd Rocm are
a bit weird (even if they work well)
