--- Comment #15 from Jari Tahvanainen <jari.tahvanainen at intel.com> ---
I know Chris that you say that we are half a way to fixing the regression, but
measurements with OglDrvCtx (from Synmark 7) done with Ubuntu kernels are
showing that one might have recovered from the regression reported dec-2014. If
one sets Aug-2015+fixes as the baseline (100%) then one :
4.2.0-42-generic - Aug-2015+fixes - 100%
4.4.0-21-generic - Jan-2016+fixes - 187%
4.8.0-46-generic - Oct-2016+fixes - 173%
4.10.0-19-generic - Feb-2017+fixes - 206%
So I will remove regression related tags from this issue, and proposing this to
be closed as fixed. Chris+Jani+Eero - if you agree then please change status to
closed, if not then please set status=REOPENED.
