Comment 4 Laura Abbott 2017-01-17 01:11:34 UTC 
*********** MASS BUG UPDATE **************
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 25 kernel bugs.
 
Fedora 25 has now been rebased to 4.9.3-200.fc25.  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 26, and are still experiencing this issue, please change the version to Fedora 26.
 
If you experience different issues, please open a new bug report for those.
Comment 5 Andrew Stiegmann 2017-01-17 04:19:19 UTC 
Stopped seeing issues on the kernel-4.8.16-300.fc25.x86_64 release.  Currently running 4.9.3-200.fc25 and have not observed issues here either.  Recommend closing.
Comment 6 Laura Abbott 2017-01-17 15:16:00 UTC
