Please just attach the full dmesg and don't try and filter it. Also there should be an error state you can attach here.
Comment 3 Chris Wilson 2018-01-31 08:28:33 UTC 
Also please do try attaching the logs for the failure.

I tested with and without guc again with tests:

Comment 19 Rodrigo Vivi 2018-02-28 23:32:33 UTC 
Removing CNL from the platform list. We don't even have GuC for CNL yet :/
Comment 20 Martin Peres 2018-03-16 16:44:42 UTC 
Sorry for the noise, just adding a tag to the title so as I can create a query for non-CI bugs.
Comment 21 Jani Saarinen 2018-03-29 07:10:36 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 22 Elizabeth 2018-04-09 20:58:18 UTC
