Hi I am running ath6kl-cleanup git. If I add debug_mask values with ath6kl.ko as like followings, I get the success full results, but without this, "iwlist wlan0 scan" fails. ath6kl: hw 2.0 fw 3.1.1.149 1) SCAN success with debug values: ( 0xc44,c40,40) $ insmod ath.ko $ insmod ath6kl.ko debug_mask=0x40 $ ifconfig wlan0 up $ iwlist wlan0 scan 2) SCAN failure $ insmod ath.ko $ insmod ath6kl.ko $ ifconfig wlan0 up $ iwlist wlan0 scan With this case, there is no coming event "WMI_SCAN_COMPLETE_EVENTID". After receiving "ath6kl: WMI_EXTENSION_EVENTID" iwlist shows error message: wlan0 Failed to read scan data : Resource temporarily unavailable Thanks Sangwook -- 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
