--- Comment #15 from Stefano Cipriani <cip91sk at gmail.com> ---
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 != current_lane_width) {
        if(new_lane_width == 8)
                new_lane_width = 4;

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