*********** 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 3.13.4-200.fc20.  Please test this kernel update 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 5 Robert Tucker 2014-02-24 16:09:31 UTC 
Yes, thanks, this bug seems fixed in the 3.13.4-200.fc20 kernel (and the 3.14.0-0.rc3.git5.1.fc21 kernel).

It also seems to have fixed spluttering/stuttering audio when playing Flash videos in web pages (which I didn't report).
