--- Comment #53 from Kadir <fd at colakoglu.nl> ---
Just updated to Fedora kernel 4.10.5-200.fc25.x86_64.

Until kernel 4.9.XX it said:

[drm_kms_helper]] *ERROR* [CRTC:26:pipe A] flip_done timed out

now it says:

[drm:drm_atomic_helper_commit_cleanup_done [drm_kms_helper]] *ERROR*
[CRTC:31:pipe A] flip_done timed out

I still get the timeouts, journalctl says:
