Originally reported here:
<a class="bz_bug_link 
          bz_status_REOPENED "
   title="REOPENED - [IGT][SNB only] dmesg-warn [CRTC:37:pipe A] flip_done timed out and vblank wait timed out on crtc 0"
   href="show_bug.cgi?id=104573#c12">https://bugs.freedesktop.org/show_bug.cgi?id=104573#c12</a>

With Linux 4.15 it was easy to reproduce and with cod/tip/drm-tip/2018-03-08
(fc93d196b8e428bc5a186bde78f412aa30081f38) it's now harder to reproduce, but
still possible. I no longer can reproduce issue with rotate, but still can
reproduce issue with screen turn off/turn on.

How issue was reproduced:
On Ubuntu 18.04 x86_64 with Gnome 3.28 Beta.
In Gnome Shell Wayland session.
With boot option intel.psr=1
Dell 7140 (M-5Y71) internal display is connected via eDP.

dmesg with "intel.psr=1 drm.debug=0x1e log_buf_len=1M" boot options is
attached.</pre>
