*** Bug 1600287 has been marked as a duplicate of this bug. ***
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.
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and let us know if the bug is still present on the latest kernel. (Please note: sometimes bugs get mistakenly closed during our mass closing. If you think your bug was closed in error please reopen)
The needinfo request[s] on this closed bug have been removed as they have been unresolved for 1000 days
