The slowdown-bug is also valid in Kernel 3.14.3.200-fc20.
Comment 5 Stefan Gies 2014-05-10 23:05:57 UTC 
This error is only valid in MATE-Gui. The error is not valid if I install Gnome3 fresh from a live-DVD.

*********** 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 20 kernel bugs.

Fedora 20 has now been rebased to 3.17.2-200.fc20.  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 21, and are still experiencing this issue, please change the version to Fedora 21.

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 over 3 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
