Comme= nt # 15 on bug 10255= 3 from Stefano Cipriani 
So I had time to try said patch on amdgpu and I don't get any =
more errors.
However lspci always says:

LnkSta: Speed 8GT/s, Width x8

I think it's a limitation of my laptop, even if I have "Width x16"=
; on "LnkCap".
However, forcing a lane width of 4 when it was set to 8, like so:

if (new_lane_width !=3D current_lane_width) {
        if(new_lane_width =3D=3D 8)
                new_lane_width =3D 4;

I could finally verify that the width was indeed changing (x8 on balanced, =
x4
on battery) and that the patch was working.
