Comment 1 Stanislaw Gruszka 2011-12-16 00:23:02 UTC

I think this is consequence of errors in channel switching code in mac80211, fixed in kernel-3.1.5-1.fc16. Can you the WARNING with that or newer kernel?

Comment 2 Felipe Contreras 2011-12-16 01:16:07 UTC

Perhaps. I haven't seen this problem in a long time, so I'll mark this as fixed.
