[V4.0-rc5 Regression] drm/intel problem

[V4.0-rc5 Regression] drm/intel problem

[Jörg Otte]

The display remains dark in V4.0-rc5 except of a small white line
at the top of the screen so I can't see anything. RC4 was good.
The latest good kernel that I know of is at least
4.0.0-rc4-00199-gb314aca.

Thanks, Jörg

I'm hoping the fix I just sent Linus is the fix for this, otherwise Daniel 
and co will look into it.

Jörg,

 can you verify/confirm that current git works for you? And if not,
maybe bisect exactly where it happened?

I had a similar problem as Jörg on my Lenovo x230, display black on -rc5
except some small colored line on the top. I updated to current git
(commit below) and everything looks to be ok after 10 minutes of
testing.

Thanks, Jörg
