Comment 1 Laura Abbott 2018-02-20 20:06:54 UTC

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  As kernel maintainers, we try to keep up with bugzilla but due the rate at which the upstream kernel project moves, bugs may be fixed without any indication to us. Due to this, we are doing a mass bug update across all of the Fedora 27 kernel bugs.
 
Fedora 27 has now been rebased to 4.15.3-300.f27.  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 experience different issues, please open a new bug report for those.

Comment 2 Jeremy Linton 2018-02-21 21:09:18 UTC

This went into 4.15-rc3 under commit 134059fd2775b (which varies from the linked email).

Clearing needinfo/marking for QA...

Comment 3 Justin M. Forbes 2018-02-22 12:49:35 UTC

Thanks for the update, will close this as current release as 4.15 is live now.
