>Description:
ath0: <Atheros 5416> mem 0xf2500000-0xf250ffff irq 16 at device 0.0 on
pci2
ath0: [ITHREAD]
ath0: AR5418 mac 12.10 RF5133 phy 8.1
if bgscan is enabled, connectivity will die when messages like
ath0: ath_chan_set: unable to reset channel 11 (2462 MHz, flags 0x480),
hal status 14
ath0: ath_chan_set: unable to reset channel 13 (2472 MHz, flags 0x680),
hal status 14
ath0: ath_chan_set: unable to reset channel 10 (2457 MHz, flags 0x480),
hal status 14
ath0: ath_chan_set: unable to reset channel 12 (2467 MHz, flags 0x680),
hal status 14
ath0: ath_chan_set: unable to reset channel 11 (2462 MHz, flags 0x480),
hal status 14
ath0: ath_chan_set: unable to reset channel 13 (2472 MHz, flags 0x680),
hal status 14
ath0: ath_chan_set: unable to reset channel 10 (2457 MHz, flags 0x480),
hal status 14
appear in syslog.
Disabling bgscan (ifconfig wlan0 -bgscan) removes symptoms.
