Comment 5 Jani Saarinen 2018-03-29 07:10:00 UTC 
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.
Comment 6 Elizabeth 2018-04-06 22:28:10 UTC 
This is still valid for SKL, KBL and BXT:

Thanks Martin!

I didn't know was failing on GuC...
I see that the GuC seems to be scheduling stuff with an invalid context id :(
Not really looking forward to debug a blackbox...
