I ran some tests and i believe i found the reason for these messages. Although typically no other message appears before these lines i tried to replicate their appearance and noticed the following: [ 480.600000] eth0: link down [ 480.600000] br-lan: port 1(eth0) entered disabled state [ 482.490000] eth1: link up (100Mbps/Full duplex) [ 489.320000] batman_adv: bat0: Changing gw mode from: client to: server [ 1078.250000] net_ratelimit: 982 callbacks suppressed [ 1093.550000] net_ratelimit: 169 callbacks suppressed [ 1337.700000] net_ratelimit: 397 callbacks suppressed [ 1850.070000] device mon0 entered promiscuous mode [ 1942.320000] net_ratelimit: 218 callbacks suppressed [ 3626.890000] device mon0 left promiscuous mode [ 4551.240000] net_ratelimit: 2 callbacks suppressed [ 5324.840000] net_ratelimit: 20 callbacks suppressed [11319.580000] net_ratelimit: 5171 callbacks suppressed [12768.620000] net_ratelimit: 1969 callbacks suppressed [12921.550000] device mon0 entered promiscuous mode [12941.440000] device mon0 left promiscuous mode I am using horst - git-1 and due to personal convenience i have added: iw dev wlan0 interface add mon0 type monitor to /etc/rc.local leaving me only to type horst -i mon0 every time i need to execute it. net_ratelimit messages started to appear after some revision i used and i was already using horst as described. In my last tests to try to replicate the same net_ratelimit messages as usual and i removed the mon0 interface. i did not see net_ratelimit messages anymore while trying to replicate the issue. Perhaps http://nbd.name/gitweb.cgi?p=aa-mac80211.git;a=summary which replaced all files from AA mac80211 and hostapd directories needs a patch or a fix somewhere. If so i am ready to test any ideas. > > - FElix > _______________________________________________ openwrt-users mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-users
