please attach dmesg output from both working 5.15.4-1.mga8 and non-working 5.15.6-2.mga8 Thank you François for the report. Thanks for jumping in, Thomas. Assigning to 'kernel'. Assignee:

dmesg on kernel 5.15.6 (not working)
Thats interesting... amdgpu does not show up at all in 5.15.6 dmesg. if you boot 5.15.6, switch to console (Ctrl-Alt-F3), log in as root, and try to load it manually with "modprobe amdgpu", does it complain about anything then ? You might have to check dmesg for any output Created attachment 13048 [details]
dmesg on kernel 5.15.6 (manual modprobe)
Thanks for the suggestion.
When loading the amdgpu module with modprobe, the X server immediatly starts, and everything looks fine afterward.
So, it's strange that the module is not loaded automatically at startup with this kernel.
Finally, my old radeon is working again in kernel-server-5.15.6-2.mga8-1-1.mga8 . Thanks for the update. Status:
