[Armadillo:06009] interfacesファイルの変更でkernel panic

[千葉慎也]

千葉と申します。Armadillo-400を使用し評価しています。

初歩的な箇所の質問ですみません、/etc/config/interfaceを書き換えて、固定IPにて通信を
行いたいのですが、書き換えてifupするとKernel panicが発生してしまいます。
＜順序＞
viにて/etc/config/interfacesを以下の通り書き換えます。

auto lo eth0
iface lo inet loopback
iface eth0 inet static
  address 192.168.1.1
  netmask 255.255.255.0
  network 192.168.1.0
  broadcast 192.168.1.255
  gateway 192.168.1.254

次に

ifdown eth0

最後に

ifup eth0

すると

となり停止します。
原因わかりますでしょうか。よろしくお願いします。
