Intel GPU Crash Dump
When this issue happens, the X server and gdm process terminates and you end up
back at the login screen. The system itself is not hung, but you lose your
desktop session.
Kernel: 3.10.0-693.11.1.el7.x86_64
Linux Distro: RHEL 7.4
Hardware: Dell XPS 13 9350
Display Connector: Just the laptop display
I have attached a GPU crash dump.
In addition, here are the relevant log entries from /var/log/messsages for the
last 2 times the GPU hung.
=====================

Feb 20 16:35:12 xecho kernel: [kern.info][250168.455916] [drm] GPU hangs can
indicate a bug anywhere in the entire gfx stack, including userspace.
