After upgrading to kernel 5.13.4 (from 5.12.15, on Arch Linux), I’ve realized my AMD dGPU was not powering off anymore resulting in increased power consumption, heat and noise (because of the fan trying to dissipate the heat).
I’ve compared kernel dmesg on both kernels, and I’ve found related differences:

I’ve attached both excerpt matching the diff above.
FWIW, this is a Dell Precision 5530 2-in-1 with a Kaby Lake-G CPU, which has an Intel HD 630 iGPU as well as an AMD Polaris 22 MGL XL [Radeon Pro WX Vega M GL] dGPU.
Please tell me if there is anything else that I can provide in order to fix this.
