Originally reported here:
https://bugs.freedesktop.org/show_bug.cgi?id=104573#c12

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.
