First of all. Sorry about spam.
This is mass update for our bugs. 

Sorry if you feel this annoying but with this trying to understand if bug still valid or not.
If bug investigation still in progress, please ignore this and I apologize!

If you think this is not anymore valid, please comment to the bug that can be closed.
If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug.

This is still valid with these tests on BDW and HSW:

Chris, or someone is this could to be fixed / planned to be fixed?

Chris, any help here?

It's a configuration issue in their kernel; e.g. the device is being kept alive by a child device.
