*********** 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 23 kernel bugs.
 
Fedora 23 has now been rebased to 4.7.4-100.fc23.  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 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25.
 
If you experience different issues, please open a new bug report for those.
Comment 4 Per Sjoholm 2016-09-24 15:54:16 UTC 
I did a rsync to a new filesystem and the problem went away.
I don't have the knowledge to debug btrfs have got any advice on howto

I still have the H/W but it's not in use anymore and it's running F24.

Please close the Bug.
