So it mentions cfg80211, but I'm not sure how that factors into things. What can I do to look into this further? I have no problem digging into the code if I'm given some pointers on which files to look at, how to get a stacktrace and how I can compile/test my changes. I really wish gdb was in the repositories :-(
