The inline comment explains what is going on - on the ar5416 and ar9160 (at least) writing -50 to the CCA registers during Noise Floor calibration can result in the RX side going deaf. This has been tested on an SR-71 (AR9160 based) 11n MiniPCI card. The initial NF calibration on startup takes longer than the initial CCA register loading. It may be possible this occurs during periodic recalibrations. Obtained from: Linux END
