            Bug ID: 99057
           Summary: non-recoverable hang/freeze following WARNING: CPU: 3
                    PID: 783 at drivers/gpu/drm/i915/intel_display.c:14189

           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Intel

kernel-4.9.0-0.rc8.git0.1.fc26.x86_64
libwayland-server-1.12.0-1.fc25.x86_64

Reproducible: non-deterministic but is a regression, doesn't ever happen with
4.8.x kernels. Uncertain if Wayland is the trigger since I'm pretty much only
using Wayland.

Summary: Walk away from the laptop for some period, upon return there's a
traceback on the screen, and the system is unresponsive. I can't get to a VT
and I can't remotely login via ssh. Must be hard reset.
