radeon vs amdgpu drivers

Hello everybody,

I run this morning into an issue, which caused a hang of my Wayland session on 
Debian 13.

journalctl revealed:
radeon 0000:00:01.0: bo va 0x000010e594 conflict with (bo 0x000010e594 
0x000010e5a3)

(among other radeon reports).

I have a Kabini APU (GCN 2nd gen / "Sea Islands"):

rd@gigabyte:~$ lspci -nn | grep VGA 00:01.0 VGA compatible controller [0300]: 
Advanced Micro Devices, Inc. [AMD/ATI] Kabini [Radeon HD 8400 / R3 Series] 
[1002:9830] rd@gigabyte:~$

I switched to the amdgpu kernel module:

# echo "options amdgpu cik_support=1" | tee /etc/modprobe.d/amdgpu.conf
# echo "options radeon cik_support=0" | tee -a /etc/modprobe.d/amdgpu.conf
# update-initramfs -u -k all
# reboot

So far I did not observe any issues, it even resolved a framebuffer corruption 
issue after resume from suspend (had to switch to a virtual console and back 
to wayland to have a useful screen output again).

Is amdgpu generally seen as the better kernel module for my hardware?

If yes, would it make sense to make it the default? As a side note, I upgraded 
the system from previous Debian stable releases, so it might be that it is the 
default on new installations...

If there is a better mailing list, please redirect the responses to that list.

Many thanks for the great Debian distribution
Rainer
