I have a laptop with this device which periodically spontaneously loses connection, gets into 'no carrier' state. '/etc/rc.d/netif restart' doesn't help. I believe it brings it down and up too fast. '/etc/rc.d/netif stop && sleep 3 && /etc/rc.d/netif start' usually helps. But this command sometimes also leaves it into 'no career' state. I also saw the situation when after the hot reboot ath0 came up with messages 'device timeout', and was never usable. Yuri 9.2-STABLE ath0: <Atheros 5424/2424> mem 0x8b100000-0x8b10ffff irq 18 at device 0.0 on pci4 ath0: AR2425 mac 14.2 RF5424 phy 7.0
