Comment 3 Jani Saarinen 2019-06-19 11:28:47 UTC 
From Maarten: 
Impact to user: lot of dmesg spam about WARN_ON, possibly denial of service if it triggers too many times. Fix is on the mailing list.
Comment 4 Jani Saarinen 2019-10-03 15:00:57 UTC 
Maarten, where we are on this ?
Comment 5 Jani Saarinen 2019-10-03 15:03:32 UTC 
Resolving this as not seen on ICL lately. Last time CI_DRM_6470_resume almost 3 months ago.
