Hi,

When booting my Asus Zenbook UX31A-R4003X with an external monitor connected
using micro HDMI, I get the following errors and the PC is somewhat stuck.
Plugging the monitor after booting does work.

[drm:intel_dp_start_link_train [i915]] *ERROR* [CONNECTOR:67:eDP-1] Link
Training failed at link rate = 270000, lane count = 2
[drm:ironlake_crtc_enable [i915]] *ERROR* mode set failed: pipe A stuck
[drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR*
[CRTC:39:pipe A] flip_done timed out
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[CRTC:39:pipe A] flip_done timed out
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[CONNECTOR:67:eDP-1] flip_done timed out

[PLANE:28:primary A] flip_done timed out
[drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR*
[CRTC:39:pipe A] flip_done timed out

I'm using Fedora 28 running Linux 4.17.14-202.fc28.x86_64. Please ask if you
need more informations and please tell me if my problem is not related to this
bug and I need to open a new bug report.

Regards
