--- Comment #4 from Jani Nikula <jani.nikula at intel.com> ---
Adam, I barely spent a minute looking at the bug in a firehose stream of bugs.
My only point was, you're bringing up i915.enable_fbc in a way that might lead
people (people as in other developers, not users) astray when looking at this
bug. FBC is disabled by default, therefore i915.enable_fbc=0 is a no-op, and
shouldn't change anything for the issue you're seeing.
