I've tried 3.3-rc5 kernel with similar results. I notice a lot of these popping up in /var/log/messages as well: ieee80211 phy0: wl0: brcms_c_d11hdrs_mac80211: txop exceeded phylen 155/256 dur 1746/1504 ieee80211 phy0: wl0: brcms_c_d11hdrs_mac80211: txop exceeded phylen 130/256 dur 1546/1504 ieee80211 phy0: wl0: brcms_c_d11hdrs_mac80211: txop exceeded phylen 130/256 dur 1546/1504 any ideas how to solve this?
