After LSPCON FW update on SKL the error haven't been saw again. We'll be monitoring the test and will reopen if needed.

Comment 14 Jani Saarinen 2018-03-29 07:11:23 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.

Marta, have you seen this on SKL on CI?
Comment 19 Martin Peres 2018-09-04 11:22:57 UTC 
We cannot get updates anymore from Elizabeth, and we have other bugs tracking LSPCON issues. Closing as INVALID.
