Comment 2 Stanislaw Gruszka 2013-08-23 08:00:34 UTC 
I think, this should be fixed on 3.10 kernel. Can you still reproduce this particular trace when suspending on 3.10 ?
Comment 3 Justin M. Forbes 2013-10-18 21:21:48 UTC 
*********** 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 18 kernel bugs.

Fedora 18 has now been rebased to 3.11.4-101.fc18.  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 19, and are still experiencing this issue, please change the version to Fedora 19.

If you experience different issues, please open a new bug report for those.
Comment 4 Vinod Kutty 2016-01-26 17:18:02 UTC 
Filling this out for completeness (thanks to the nagware).

Haven't experienced the problem in newer kernels.

However, NB: the frequency was far higher on a corporate network with WPA2 Enterprise and lots of access points. I don't have the same setup to test with further.
