Dmesg after first boot

Since kernel 4.7 (at least, see below), whenever I resume from hibernation and try to use xrandr to manipulate any video output, my screen goes off and on again and this message is displayed:
xrandr: Configure crtc X failed

With no effect happening, whatever the xrandr command I issued.

This has been confirmed in kernel 4.7, 4.8, 4.9 and 4.10-rc8 drm-tip that I've just built now up to commit 890e171e84eb11944701de9d53c1162dd5c38142.

I can't recall exactly, but I'm pretty sure 4.6 has this issue, and MAYBE 4.5.
I am pretty sure however that 4.4 works just fine as I've been using that for a long time.

This is the same issue described here, and already bisected in October last year by another user:
https://lkml.org/lkml/2016/10/28/441

My hardware is a Lenovo X230 Ivy Bridge i5-3320m. Distro is Debian amd64, mix of stable and testing.

I'm attaching the dmesg logs before and after hibernation using drm-tip and drm.debug=0xf.

Problem appears to be fixed in 4.9.14. This can be closed.
