I have stopped and started the network repeatedly using both my home router
and my hot-spot and I can't get it to fail. It associates the first time
every time. I'm about ready to chalk up my one failure with the new kernel
as a fluke. I'll continue testing later today, but this one may be resolved.

I'll also rebuild my kernel without the debug options just in case the
slight timing change had some impact on this.

Thanks to both Glen and Adrian for helping me look into this. Still have no
idea why IWN_DEBUG didn't seem to work.
