[GTALUG] Last Ubuntu OS Update Breaks ffmpeg

[Russell Reiter]

Could be a power state issue. I just recently added
intel_pstate=skylake_hwp to my grub while working on my own build. If it is
a similar issue, perhaps the instructions on this page will help.

IIRC I added this to F27 but not yet to F28, just to make sure I didn't
break anything. My video stuttering issue is really with F28.
