My Fon will reboot after power off correctly if I use this method to flash:
ip_address -l 192.168.1.254/24 -h 192.168.1.166
fis init
load -r -v -b 0x80041000 openwrt-atheros-2.6-root.jffs2-64k
fis create -b 0x80041000 -f 0xA8030000 -l 0x002C0000 -e 0x00000000 rootfs
load -r -v -b 0x80041000 openwrt-atheros-2.6-vmlinux.lzma
fis create -r 0x80041000 -e 0x80041000 -l 0x000E0000 vmlinux.bin.l7
reset
