.. hah, I should've not edited the patch by hand. It should patch sys/dev/ath/ath_hal/ar5416/ar5416_ani.c, obviously. That should quieten the OFDM errors, but I think this a symptom of something else on the radio side of things. I'll do some more tinkering in a couple of days. I remember changing the AR9280 calibration code to match what's in the Linux and Atheros reference drivers; maybe the older AR9280 calibration code (which does a few AGC calibrations, rather than just one) works better in this instance.
