https://bugzilla.redhat.com/show_bug.cgi?id=585072 I suspect this stems from here: commit a9f042cbe5284f34ccff15f3084477e11b39b17b Author: Ming Lei <tom.leiming@gmail.com> Date: Sun Feb 28 00:56:24 2010 +0800 ath9k: fix lockdep warning when unloading module
Perhaps I spoke too soon. The problem, which was repeatable since installing Fedora 13 beta has disappeared yesterday after posting. Perhaps it was the reboot. Although kernel was not updated, I believe NetworkManager had been. I had not rebooted in a week. NetworkManager-gnome-0.8.0-7.git20100422.fc13.x86_64
The reporter of the Red Hat bugzilla referenced in comment 7 reports that reverting the patch mentioned there resolves his issue. Ming Lei, do you have a proposal for addressing both the _local_bh_enable_ip warning and the original lockdep warning?
Hi John, Same with 15761. Johannes has commented it already, please see http://marc.info/?l=linux-wireless&m=127088247304187&w=2 Seems there is still some fix not merged to stable tree. Thanks,
*** This bug has been marked as a duplicate of bug 15761 ***

Alright, reopening to address suspend/resume problem -- please ignore the ath9k-related messages in the preceding comments...

Please keep the original kernel version. It's useful to know when the bug appeared without going into the entry.
Created attachment 26872 [details] Message in console
Please test 2.6.37-rc8 and report back.
Now work fine, thanks

You seriously reopened a bug from over two years ago? Whatever problem you are having, please open a new bug with all the relevant information you can provide. Hijacking a long-dead bug seems at best unproductive...
