We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 28 kernel bugs. Fedora 28 has now been rebased to 4.18.10-300.fc28. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 29, and are still experiencing this issue, please change the version to Fedora 29. If you experience different issues, please open a new bug report for those.
I'm afraid I can't exactly remember what this issue was. I am one of those people who report bugs without completely understanding what the problem is (or, as in this case, without even having a clue), hoping somebody else will be able to make sense of them. But if this issue was persistent I would have remembered it, so it's probably safe to assume it has been fixed now. Thanks! I am still using Fedora 28 by the way.
thanks for letting us know. I think it makes sense to close this for now.
