--- Comment #3 from Ander Conselvan de Oliveira <conselvan2 at gmail.com> ---
Before suspend, VGA is enabled on pipe A and eDP is enable on pipe B. After
suspend/resume, the BIOS sets up eDP on pipe A and VGA on pipe B, and the force
restore modeset fails, since it tries to enable VGA on pipe A without disabling
pipe B.
