Hi, Doing an "iwconfig wlanX channel 1" on current wireless-testing _without_ doing an "iwconfig wlanX mode XXX" previously freezes the current process. No debug messages (but I don't have manu debugging options enabled, like lock debugging). Doing an "iwconfig wlanX mode XXX" before changing the channel fixes the issue. This happens both on an up and down device. -- Greetings, Michael. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
