X terminating is entirely unconnected with that *ERROR*.
Are you sure? Whenever X crashed, that inteldrv kernel message was showing up in dmesg. Affected versions: xorg-x11-server-1.14.3.901 xf86-video-intel-2.99.906-4.1.x86_64 Working versions: xorg-x11-server-1.13.2 xf86-video-intel-2.20.19
Can you please attach your Xorg.0.log with the crash information?
