could this be duplicat of 1435837

Comment 2 Laura Abbott 2018-02-28 03:38:17 UTC

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale. The kernel moves very fast so bugs may get fixed as part of a kernel update. Due to this, we are doing a mass bug update across all of the Fedora 26 kernel bugs.
 
Fedora 26 has now been rebased to 4.15.4-200.fc26.  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 27, and are still experiencing this issue, please change the version to Fedora 27.
 
If you experience different issues, please open a new bug report for those.

Comment 3 Knut J BJuland 2018-03-16 20:56:18 UTC

Still present in kernel  4.15.9-300.fc27.x86_64
