Hi Mark,

Yes, I was using xf86-video-intel, but I tried modesetting as well:

1. I added modesetting to /etc/X11/xorg.conf 
Section "Device"
    Identifier  "Intel Graphics"
    Driver      "modesetting"

2. xrandr --list-providers confirmed that I was using modesetting:
Providers: number : 1
Provider 0: id: 0x45 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 3
associated providers: 0 name:modesetting

3. glxinfo showed DRI3
LIBGL_DEBUG=verbose glxinfo | grep libgl
libGL: Using DRI3 for screen 0

Unfortunatelly after some time driver crashed:

[Fri Dec  9 15:35:54 2016] [drm] stuck on render ring
[Fri Dec  9 15:35:54 2016] [drm] GPU HANG: ecode 7:0:0x85dffcfc, in chrome
[1877], reason: Ring hung, action: reset
[Fri Dec  9 15:35:54 2016] [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
[Fri Dec  9 15:35:54 2016] [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
[Fri Dec  9 15:35:54 2016] [drm] drm/i915 developers can then reassign to the
right component if it's not a kernel issue.
[Fri Dec  9 15:35:54 2016] [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.
[Fri Dec  9 15:35:54 2016] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
