ath0: bb hang detected (0x1), resetting

Hi. Sometime I receive this message on one of access point:
ath0: bb hang detected (0x1), resetting
After that connection restored only if I turn off wifi by hard button and turn on again.

ath0: <Atheros 9287> mem 0xe0500000-0xe050ffff irq 18 at device 0.0 on pci10
ath0: [HT] enabling HT modes
ath0: [HT] enabling short-GI in 20MHz mode
ath0: [HT] 1 stream STBC receive enabled
ath0: [HT] 1 stream STBC transmit enabled
ath0: [HT] 2 RX streams; 2 TX streams
ath0: AR9287 mac 384.2 RF5133 phy 15.15
ath0: 2GHz radio: 0x0000; 5GHz radio: 0x00c0


Do you have any ideas? What I can provide to solve this issue?
