"link down" is caused by a thread of IWK driver that monitors errores from 4965 chip. This thread will turn down and restore link when some errores from 4965 card occur. Through analyzing dmesg messages, "ieee80211_crypto_enmic failed" may make 4965 card cause errores. Judy, could you please give more information about ieee80211_crypto_enmic function in net80211 module?
