Are these ath0 kernel messages harmless?

[nxjoseph]

Hi,

I had the chance to plug my AR9462 PCI-E Ethernet Card to my Desktop PC back in and this time I've noticed kernel messages related to my wireless interface.

[16] wlan0: link state changed to UP
[16] ath0: ath_rate_tx_complete: ts_rate=27 ts_finaltsi=0, final_rix=0
[16] ath0: bad series0 hwrate 0x1b, tries 1 ts_status 0x0

[236] ath0: bad series0 hwrate 0x1b, tries 1 ts_status 0x0
[240] ath0: ath_rate_tx_complete: ts_rate=27 ts_finaltsi=0, final_rix=0
[240] ath0: bad series0 hwrate 0x1b, tries 1 ts_status 0x0
[20250] ath0: ath_rate_tx_complete: ts_rate=27 ts_finaltsi=0, final_rix=0
[20250] ath0: bad series0 hwrate 0x1b, tries 1 ts_status 0x0

Are these harmless? Is there way that I can disable them so I won't see them? Thanks in advance.
