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.

Most of the data here relates to CNL, which is no longer a platform we test (and may have been due to quirks of CNL early hardware rather than software). There is a report of underruns on GLK reported here, but the recent CI results for those tests are all clean and we don't have a CIbuglog issue entry for this, so I think we can mark this as resolved.
