machine configuration

After installing the kernel 6.7.6.arch1-1-x86_64, I'm unable to control the screen brightness (I can move the slider but nothing happens)
and there are no wifi devices available.

the machine configuration reports kernel 6.7.5 because it was made after a rollback to a previous working kernel.
The boot messages are relative to the not working 6.7.6 kernel.

For display brightness you probably want to file a bug report here:

For WiFi breakage regression testing is advised:

The way this bug report is filed, it's unactionable.

Please file a bug report in the AMDGPU bug tracker and a new one for your WiFi.
