Comment (by anonymous):
I've also very recently (since last week) noticed spontaneous reboots upon
"heavy" WiFi activity on a TP-Link WDR3600 running CC trunk. The
OpenWrt/WDR3600 2.4GHz radio0 wlan0 is configured as a station to a
consumer AP in a very noisy environment so the link is very unstable.

However I can't reproduce the reboots, OpenWrt may reboot 3 times within
10 minutes or run stable for hours.
