Description Oded Arbel 2011-04-25 17:16:07 UTC

+++ This bug was initially created as a clone of Bug #413641 +++

This problem appears to be recurring in Fedora 15 - I get the above error in my logs every couple of minutes even though the wireless network connects and works fine (I think - I have dropped connections, but that may also be my ISP).

Here is an example output from messages:
