dmesg output after wakeup

When waking up from hibernate (suspend-to-disk), the computer is frozen for a
few minutes. Then the screen turns black and the computer unfreezes. This is
reproducible for me.

I'm on a Lenovo ThinkPad T460p with Intel GPU running Gentoo Linux.

Software versions:
* Linux Kernel 4.9.0
* xf86-video-intel from git (2016-12-06)
* Xorg 1.18.4

Attachments:
* Excerpt from dmesg
* Xorg.log
* GPU crash dump from /sys/class/drm/card0/error
