Re: [PATCH 1/2] drm: introduce page_flip_timeout()

The normal suspend-resume path doesn't seem to be enough (I end up
hitting [0] and [1] actually). However, if I force it to take the reset
path (using
amdgpu_device_lock_reset_domain()/amdgpu_device_unlock_reset_domain()),
that does seem to do the trick.
