The ath9k _is_ running with regdomain == 0x0 (instead of the 0x6a world-domain in it's eeprom). NIC is Sparklan 127N (AR9830 chipset). Kernel is 2.6.39-wl+. The code that is complaining is: if (WARN_ON(!tid_tx)) { #ifdef CONFIG_MAC80211_HT_DEBUG printk(KERN_DEBUG "addBA was not requested!\n"); #endif goto unlock; } We were associating 128 stations using another AR9380 system as virtual STA interfaces. Aside from scary messages, the system seems fine, and it quit spewing these messages a short time after bringup.
