        <pre>Linux 4.8.13-1-ARCH x86_64
xorg-server 1.19.1-1

Since updating Xorg to 1.19.1-1 it core dumps multiple times a day. Multiple
users reporting this issue. Removing the xf86-video-intel driver and going back
to modesetting seems to make the problem slightly less. However some users
still have crashes then. So it seems to be something in Xorg. But seems to be
triggered randomly, haven't been able to pinpoint it to a specific action. Just
the entire DE/Xorg crashing and the screen going blank.

I was using two monitors (Laptop 2560x1600 + Monitor 2560x1440 connected via
HDMI). 

Full core dump:

Jan 16 10:50:04 systemd-coredump[6294]: Process 1600 (Xorg) of
user 0 dumped core.
