I'd like to see what = it's saying during boot around it checking the EEPROM/OTP contents. It's = possible there's some work around required for this NIC. He speaks! Thanks for taking the time. I just realized that = ath_hal_printf doesn=E2=80=99t prepend =E2=80=9Cath%d=E2=80=9D so I=E2=80=99= ve been missing those messages when grep-ing.
