Here's logs from a station system that had a problem of this nature. Since it should not be doing any beaconing, I guess the root cause of at least this particular problem is different. This is with our firmware and hacked ath10k driver, so of course it is possible it is not an upstream problem. Kernel is 3.14, with most of the ath10k patches from 3.15 backported to it, plus additional patches. http://dmz2.candelatech.com/git/gitweb.cgi?p=linux-3.14.dev.y/.git;a=summary Jun 22 10:00:00 localhost kernel: ath10k: Creating vdev id: 0 map: 68719476735 Jun 22 10:00:00 localhost kernel: IPv6: ADDRCONF(NETDEV_UP): sta1: link is not ready Jun 22 10:00:00 localhost kernel: ath10k: Creating vdev id: 1 map: 68719476734 Jun 22 10:00:00 localhost kernel: IPv6: ADDRCONF(NETDEV_UP): sta2: link is not ready Jun 22 10:00:01 localhost kernel: ath10k: stop, state OFF Jun 22 10:00:02 localhost kernel: e1000e: eth1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx Jun 22 10:00:02 localhost kernel: IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready Jun 22 10:00:04 localhost kernel: ath10k: Target ready! transmit resources: 3 size:1792 Jun 22 10:00:04 localhost kernel: ath10k: wmi event firmware message 'P 73 V 36 T 411' Jun 22 10:00:04 localhost kernel: ath10k: wmi event firmware message 'msdu-desc: 808 sw-crypt: 1' Jun 22 10:00:04 localhost kernel: ath10k: wmi event firmware message 'alloc rem: 4332 iram: 57220' Jun 22 10:00:04 localhost kernel: ath10k: start, state going from OFF to ON Jun 22 10:00:04 localhost kernel: ath10k: Creating vdev id: 0 map: 68719476735 Jun 22 10:00:04 localhost kernel: IPv6: ADDRCONF(NETDEV_UP): sta1: link is not ready Jun 22 10:00:05 localhost kernel: ath10k: stop, state OFF Jun 22 10:00:08 localhost kernel: ath10k: failed to receive initialized event from target: 00000000 Jun 22 10:00:08 localhost kernel: ath10k: failed to wait for target to init: -110 Jun 22 10:00:08 localhost kernel: ath10k: failed to power up target using warm reset: -110 Jun 22 10:00:08 localhost kernel: ath10k: trying cold reset Jun 22 10:00:08 localhost kernel: ath10k: target took longer 5000 us to wake up (awake count 1) Jun 22 10:00:11 localhost kernel: ath10k: failed to receive initialized event from target: ffffffff Jun 22 10:00:11 localhost kernel: ath10k: failed to wait for target to init: -110 Jun 22 10:00:11 localhost kernel: ath10k: device crashed - no diagnostics available Jun 22 10:00:11 localhost kernel: ath10k: target took longer 5000 us to wake up (awake count 2) Jun 22 10:00:11 localhost kernel: ath10k: failed to wake up target: -110 Jun 22 10:00:11 localhost kernel: ath10k: failed to power up target using cold reset too (-110) Jun 22 10:00:11 localhost kernel: ath10k: Could not init hif: -110 (state OFF) Jun 22 10:00:11 localhost kernel: ath10k: target took longer 5000 us to wake up (awake count 2) Jun 22 10:00:11 localhost kernel: ath10k: failed to wake up target: -110 Jun 22 10:00:11 localhost kernel: ath10k: failed to reset target: -110 Jun 22 10:00:11 localhost kernel: ath10k: failed to power up target using warm reset: -110 .....
