I have flashed the picostation 2 with the actual trunk revision. Sometimes, I'm getting stuck beacon messages that do not stop, ~2-3 per second. The AP isn't visiible if scanned from outside if that happens. I'm using the default wlan configuration, with "disabled" commented out. I made a very interesting observation. Whenever I do a "iwlist scan" on the picostation, the channel is changed randomly, and whenever channel 6 is chosen, the stuck beacon messages appear. I have tried this on three different picostations, even with different revisions, the stuck beacons only appear when channel 6 was chosen. I have made a lot of trials, the problem never appeared on other channels.

The problem can be reproduced easily by issuing "iwlist scan" until the messages appear. Sometimes it needs a lot of trials until channel 6 is choosen.
