--- Comment #23 from Martin Andersen <martin.x.andersen at gmail.com> ---
I'm getting this constantly on a i5-3570 (IVB/HD4000) system; currently running
the most recent kernel (3.16.0-031600-generic #201408031935). System is
becoming near-unusable.
Problem was also present on 3.14.4.
During boot I also get the 'pipe_off wait timed out' / 'failed to disable
transcoder A' errors, which is not critical but hangs the system for a time --
