The follow commands cause a reboot on a WRT160NL:
cd $1 echo netdev trigger echo $2 device_name echo $3 mode
I've noticed similar problems on an TP-Link tl-wr941nd.
Do you guys have a serial console connected? Do you get a kernel crash
log when the system reboots?
If so, then please rebuild with Compile the kernel with symbol table
information enabled under Global build settings and send over all the
kernel messages that you're receiving.
