*********** 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 19 kernel bugs.

Fedora 19 has now been rebased to 3.13.5-100.fc19.  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 3 Justin M. Forbes 2014-06-23 14:41:42 UTC 
*********** MASS BUG UPDATE **************
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 4 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.
Comment 4 Mario García H. 2014-09-21 16:56:52 UTC 
I'm getting exactly the same warning from Fedora 20 (stable and updates-testing). Linux 3.16.3-200.fc20.x86_64 #1 SMP Wed Sep 17 22:34:21 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Also I have many problems trying to get a stable clock source whenever the laptop goes to sleep. Time jumps even years ahead (eg. 2019). 

I really want to stick with Fedora, so ask me for whatever info you need in order to resolve this bug.
