Not sure what happened, but my log appeared to be full of these messages:

Note sure what caused it, but others have had it in the past as well.
Other symptoms:
- br0 network becoming slower and slower on download speed (but not on upload speed; in the end I had 0.5 megabit downstream and 5 megabit upstream)
- br0 ping times twice as high as normal (around 30 milliseconds on SpeedTest.net in stead of 15 milliseconds)
- WiFi (especially 2.4: eth1) becoming impossible to connect to from new connections
- packet drops
I thought they were caused because of me experimenting with a Fonera 2100A -> TomadoUSB experiment, especially since my FON access point was limited to 1 megabit.
But as soon as other users started to use the LAN, I got speed complaints about the slowness.
I’ve been running the ASUS RT-N66U in Firmware Version 3.0.0.4.260 with Operation Mode:Wireless router for quite a while now, but I also noticed that it had rebooted itself recently, as the was Uptime 0 days 20 hours when I started digging in the log.
