Description PC LX 2022-09-08 12:51:02 CEST

Description of problem:

I'm seeing the following kernel WARNING message (dmesg):

WARNING: CPU: 1 PID: 412 at drivers/gpu/drm/amd/amdgpu/../display/dc/clk_mgr/dcn21/rn_clk_mgr_vbios_smu.c:98 rn_vbios_smu_send_msg_with_param+0xf1/0x100 [amdgpu]


This is a regression from kernel 5.18.15-desktop-1.mga8.

Some links that pertain to this issue:
https://bugzilla.kernel.org/show_bug.cgi?id=216092
https://gitlab.freedesktop.org/drm/amd/-/issues/2110

I don't think this causes any issues other than the mentioned WARNING message but since there seems to be a fix I think it would be a good idea to include it in the next kernel update.

Comment 2 PC LX 2022-11-18 16:12:25 CET

This issue is no longer present in the current kernel so it is probably resolved in one of the past updates.
Will mark it as resolved and reopen if it reappears.
