Comment 1 Stanislaw Gruszka 2013-03-11 12:53:58 UTC 
Please attach full dmesg for this bug report (with the warning). You can find it in .cache/abrt/spool/oops-{DATE}/ or in /var/spool/abrt/oops-{DATE}/ 

BTW, it should be attached by ABRT by default, what version of ABRT are you using?

Complete abrt oops data

Reopening this as I am providing a complete set of data.
Comment 4 Brad Hubbard 2013-05-12 02:50:35 UTC 
I saw this after disabling wireless networking via the KDE nm-applet and then reenabling. This was done after experiencing connectivity problems to the AP due to heavy usage by one of the other connected nodes.
