Comment 1 The Linux kernel's regression tracker (Thorsten Leemhuis) 2023-05-05 03:49:58 UTC 
This report here will likely not be seen by the amdgpu developers, they expect bugs to be filed here instead:
https://gitlab.freedesktop.org/drm/amd/-/issues

If you file it there, please drop a link to the report here.

BTW, did it work on earlier kernels? Which ones? there is a report about a problem in earlier kernels that sound somewhat similar (but it might be something totally different):
