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.

Code: 
[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
[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
[33] ath0: ath_rate_tx_complete: ts_rate=27 ts_finaltsi=0, final_rix=0
[33] ath0: bad series0 hwrate 0x1b, tries 1 ts_status 0x0
[222] ath0: ath_rate_tx_complete: ts_rate=27 ts_finaltsi=0, final_rix=0
[222] ath0: bad series0 hwrate 0x1b, tries 1 ts_status 0x0
[236] ath0: ath_rate_tx_complete: ts_rate=27 ts_finaltsi=0, final_rix=0
[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.

you've got a link, so it seems like they're not interfering with normal operation. judging by the function names, it sounds like the driver doesn't like the response it's getting from the card when trying to enumerate transmit rates, implying that the card wants to go faster than the driver knows how to deal with.
