Same failure in all our platforms with gpu gen 8 and down, SNB, IVB, BYT, HSW, BDW, BSW. If this is expected, test should be skipped, isn't it?

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.

Still a valid issue for BSW, BDW, HSW, BYT, IVB, SNB.
