Obsolete Bugtracker Link
In the documentation contained in the offical driver package: https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-50 the link to report bugs is still: https://bugs.freedesktop.org/ which is no longer active.
Also seen in this online available mirror of the docs: https://amdgpu-install.readthedocs.io/en/latest/install-bugrep.html
There someone already mentioned the problem: https://gitlab.com/amdgpu/docs/amdgpu-install/-/issues/1
Related: https://community.amd.com/t5/drivers-software/linux-bugtracker-no-longer-active/m-p/458882
Took me some digging to find this actual bugtracker, so updating the reference would really help.
