This ath5k is running hostapd 1:0.7.3-4 with WPA-EAP and had no clients for the 12 hours before the calibration message started, and had no clients for hours after until I tried to connect and found I couldn't. While I was unable to connect, I flipped the laptop rfkill switch and the gain calibration timeouts continued, disabling rfkill and they still continued. That's when I did a suspend to memory and resume and found it recovered. While it was working I tried rfkill and it no longer was talking after disabling rfkill, I thought it was resuming previously, but I don't use that very often. I revered the following two comments and will see if I run into any more problems. I can test patches. ath5k: We always do full calibration on AR5210 dafae6af0336958e9e2eb67cc5e4e31d6d13b308 ath5k: Calibration re-work ce169aca0d823d38465127023e3d571816e6666c Feb 24 21:54:23 Pulsar kernel: ath5k 0000:06:02.0: registered as 'phy0' Feb 24 21:54:23 Pulsar kernel: ath: EEPROM regdomain: 0x63 Feb 24 21:54:23 Pulsar kernel: ath: EEPROM indicates we should expect a direct regpair map Feb 24 21:54:23 Pulsar kernel: ath: Country alpha2 being used: 00 Feb 24 21:54:23 Pulsar kernel: ath: Regpair used: 0x63 Feb 24 21:54:23 Pulsar kernel: ieee80211 phy0: Selected rate control algorithm 'minstrel_ht' Feb 24 21:54:23 Pulsar kernel: ath5k phy0: Atheros AR2413 chip found (MAC: 0x78, PHY: 0x45) Feb 24 21:54:23 Pulsar kernel: device wlan0 entered promiscuous mode Feb 24 21:54:23 Pulsar kernel: br0: port 2(wlan0) entering forwarding state Feb 24 21:54:23 Pulsar kernel: br0: port 2(wlan0) entering forwarding state Feb 24 21:58:59 Pulsar kernel: ath5k 0000:06:02.0: registered as 'phy0' Feb 24 21:58:59 Pulsar kernel: ath: EEPROM regdomain: 0x63 Feb 24 21:58:59 Pulsar kernel: ath: EEPROM indicates we should expect a direct regpair map Feb 24 21:58:59 Pulsar kernel: ath: Country alpha2 being used: 00 Feb 24 21:58:59 Pulsar kernel: ath: Regpair used: 0x63 Feb 24 21:58:59 Pulsar kernel: ieee80211 phy0: Selected rate control algorithm 'minstrel_ht' Feb 24 21:58:59 Pulsar kernel: ath5k phy0: Atheros AR2413 chip found (MAC: 0x78, PHY: 0x45) Feb 24 21:58:59 Pulsar kernel: device wlan0 entered promiscuous mode Feb 24 21:58:59 Pulsar kernel: br0: port 2(wlan0) entering forwarding state Feb 24 21:58:59 Pulsar kernel: br0: port 2(wlan0) entering forwarding state Feb 24 23:02:31 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 1 Feb 24 23:02:31 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 2 Feb 24 23:02:40 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 3 Feb 24 23:15:37 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 2 Feb 24 23:15:37 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 1 Feb 24 23:15:37 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 0 Feb 25 08:48:40 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 1 Feb 25 08:48:40 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 2 Feb 25 08:48:46 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 3 Feb 25 08:56:35 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 2 Feb 25 08:56:35 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 1 Feb 25 08:56:35 Pulsar kernel: wlan0: moving STA xx:xx:xx:xx:xx:xx to state 0 Feb 25 19:52:50 Pulsar kernel: ath5k phy0: gain calibration timeout (2462MHz) Feb 25 19:52:51 Pulsar kernel: ath5k phy0: calibration of channel 11 failed Feb 25 19:52:52 Pulsar kernel: ath5k phy0: gain calibration timeout (2462MHz) iw wlan0 survey dump Survey data from wlan0 frequency: 2462 MHz noise: -96 dBm channel active time: 79250 ms channel busy time: 118644 ms channel receive time: 48278 ms channel transmit time: 5285 ms -- David Fries PGP pub CB1EE8F0 http://fries.net/~david/
