Hi, mac80211 (or some other part of the networking stack) triggers this warning in the NOHZ code: NOHZ: local_softirq_pending 08 08 seems to be NET_RX_SOFTIRQ. It happens, because my test driver b43 handles all RX and TX-status callbacks in process context. I guess some part of the networking stack expects RX to be in tasklet and/or softirq context. We also have a report of this warning in wl1251, so it's probably not a b43 problem. -- Greetings, Michael. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
