I am not entirely sure. At first it only happened when disassociating from the AP at work. The above trace actually appeared when associating to my home AP.

Sorry that I cannot be more precise. > Thomas, could you enable lockdep to reproduce and see if any warning > may be triggered? Sorry, I don't know what that means.
