Hi list, I am sorry if I asked this issue before or not. I meet an issue in my laptop which is using the 168c:0032, driver is ath9k. I found if I press Fn+F12 to enable/disable the wifi, the LED would take about 5 or 6 seconds to be ON or OFF. I found the in ath9k would detect the GPIO status to change the rfkill status. and also rfkill in ath9k is using polling way to monitor the status of GPIO status. In other my machines with the same module and driver (ath9k), press Fn+F12 would be easy to find out the LED is ON or OFF, would not take too long. ( probably less than 1 second ) So is there any way to find out which driver has the right to change the GPIO status ? -- 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
