--- Comment #15 from masterofamn2 at googlemail.com ---
I see the same thing as #12 on my Arch machine:

Lenovo X220i
VGA compatible controller: Intel Corporation 2nd Generation Core Processor
Family Integrated Graphics Controller (rev 09)

running 

4.11.3-1-ARCH
mesa 17.1.2-1
xf86-video-intel 1:2.99.917+777+g6babcf15-1

in dmesg, when moving/opening windows:

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

System hangs, is non-responsive for a while, then unlocks and freezes again
when for example moving windows around.
