Experiencing the bug every few days:

root@cerowrt:~# cat /etc/openwrt_release
DISTRIB_ID="CeroWrt"
DISTRIB_RELEASE="3.10.34-4"
DISTRIB_REVISION="r40361"
DISTRIB_CODENAME="toronto"
DISTRIB_TARGET="ar71xx/generic"
DISTRIB_DESCRIPTION="CeroWrt Toronto 3.10.34-4"
DISTRIB_TAINTS="no-all busybox"

root@cerowrt:~# uptime
 12:22:42 up 1 day, 18:37,  load average: 0.04, 0.04, 0.05

root@cerowrt:~# egrep -i "country|channel|htmode" /etc/config/wireless
        option htmode 'HT20'
        option country 'AU'
        option channel 'auto'
        option htmode 'HT20'
        option country 'AU'
        option channel 'auto'

Uploaded at http://zlkj.in/files/wireshark/. I filtered the captures in
wireshark for frame.time > "April 5, 2014 20:40:44" which is about 10
seconds before the bug. wlan0.cap is the capture from my laptop. ppp.cap
is from the pppoe connection on ge00.

I can ssh in and access the admin interface if I connect my laptop by an
ethernet cable. But during the failure, I can't access the admin
interface or the internet over sw00. After resetting sw00 by admin
interface on se00, I can connect over the wireless again.

I thought I disabled babel, but I'm still seeing babel packets in the
capture, so I guess disabling the "babel" networks on both radios in the
wifi tab is not enough.
