Description sylvain.bertrand 2013-12-24 21:40:59 UTC
A performance critical fix was done on radeon linux kernel driver. It's not too invasive and has a massive effect for radeon Southern Islands and Sea Islands. Please, backport it in fedora 20 kernel.
See upstream bug report.

Dave, should those go to stable?  If not, should we bring them back to Fedora anyway?

*********** 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 4 sylvain.bertrand 2014-02-24 14:58:52 UTC
Sorry but I updated my fedora 20 to rawhide.

All I can tell you is that with the 3.13.3-201.fc20.x86_64 and current rawhide mesa, the bug is gone.
