Hello everybody, I run 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 in a stable Debian release? 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 Rainer -- Rainer Dorsch http://bokomoko.de/
