+ Ram.

Can you check if this is platform- or machine-specific? I'll update the filter based on your feedback.
Comment 3 Ramalingam C 2019-04-04 13:26:12 UTC 
Martin,

This is error log corresponding to an attached panel with invalid BKSV. We can't fix this from I915.
Comment 4 Ramalingam C 2019-04-11 10:43:39 UTC 
HDCP sink connected to teh port provides the invalid BKSV. Hence HDCP authentication is expected to fail. This is not a bug in I915. Thanks.
