--- Comment #12 from Christian Hartmann <cornogle at googlemail.com> ---
on the yoga 2 851f tablet I am also trying often to get KMS working but like
with the 3.19.y branch still no luck.
I am using vanilla kernels, and also with one or two patches of /from the
fedlet image derived.
here the short debug from linux-stable v4.0.0 (and all previous versions like
rc1 till rc7 too)
