Tried it now with kernel 4.14.0-041400rc7-generic and it still appears. (Notebook sits in dock, locked the screen, let it sit for 45 minutes, came back to computer being shut down).

In /var/log/syslog I find

Nov 1 10:01:05 xxx kernel: [ 404.329288] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
