Great to hear the AMD packages are getting fixed. Thanks for copying
that here. I guess I have 3 paths to follow:
1. trying to get "Regular AMD GPU acceleration" (built-into kernel) working
(see below),
2. awaiting AMD GPU graphics acceleration (if (1) doesn't work),
3. awaiting AMD GPU compute (ROCm).

My results (let me know any other info needed):
```
username@hostname:~:0$ glxinfo | grep Accel
MESA: error: ZINK: failed to choose pdev
glx: failed to create drisw screen
Accelerated: no
username@hostname:~:0$ lspci -v -s c5:00.0
username@hostname:~:0$ uname -r
6.8.0-45-generic
username@hostname:~:0$ lspci -v | grep -i vga
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi
21 [Radeon RX 6800/6800 XT / 6900 XT] (rev c1) (prog-if 00 [VGA controller])
14:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Raphael (rev c2) (prog-if 00 [VGA controller])
```
(in case relevant, the DisplayPort 1.4 cable is plugged into the GPU --
not the motherboard's output. Display works but, alas, no hardware
acceleration.)
On (2) if we can't get (1) working, should I hope (2) will fix it? (I'm
not expecting you to know everything, just wondering what's my best path
forwards, please?)
On (3), can understand your point re. AMD needing to fix their end. As I
said above, nice to hear that's moving forwards. Thanks for the update!
p.s. deleted and reposted due to including private info -- sorry about that!

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)
