           Summary: [G45] [drm:intel_cpu_fifo_underrun_irq_handler [i915]]
                    *ERROR* CPU pipe A FIFO underrun
           Product: DRI

I've noticed that while playing the NFSIISE port on my desktop PC I get errors
such as this one on dmesg:

[  544.874379] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe A FIFO underrun

Previously, my system also hung while playing this same game on this PC, with a
different error:

[ 3641.648551] [drm:drm_atomic_helper_commit_cleanup_done [drm_kms_helper]]
*ERROR* [CRTC:29:pipe A] flip_done timed out

This is the game I'm playing:

https://github.com/zaps166/NFSIISE

I'm on Arch Linux (x86-64) and kernel 4.11.3-1-ARCH.
