I'm using openwrt in my TL-WR740N since a year, frequently reflashing. After updating to yesterday backfire RC6 (SVN), I noticed that openwrt crashes some seconds after some(most of) the WPA rekeys. This is syslog from my laptop and openwrt. Tico is my laptop and 192.168.3.1 is openwrt.

BTW, before reflashing, I was using an midle-april svn checkout of backfire without this problem.
I was running a procfs top from a ssh and the system was running with free resources;
root@router:/tmp/usr/bin# ./top -d1 top - 16:52:25 up 22 min, 0 users, load average: 0.40, 0.50, 0.47 Tasks: 38 total, 1 running, 37 sleeping, 0 stopped, 0 zombie Cpu(s): 6.7%us, 14.4%sy, 0.0%ni, 40.4%id, 26.9%wa, 1.0%hi, 10.6%si, 0.0%st Mem: 29532k total, 24368k used, 5164k free, 516k buffers Swap: 0k total, 0k used, 0k free, 4884k cached Write failed: Broken pipe
The only process that constantly uses 10-20% of CPU is luci-bwc.
I have no serial port. Is there any way to detect why the router rebooted?
