Higher iGPU memory makes it more likely, but does not eliminate it at lower settings. This is a severity dial, not an on/off switch. This makes sense if iGPU memory allocation changes how the PCI root complex manages power states during s2idle =E2=80=94 the xHCI controller at c1:00.4 shares the same PCI root as the amdgpu at c1:00.0.
