[vine-users:081104] CF-W8で無線LAN利用時にエラー

[Tatsuo Ishii]

石井と申します。

Panasonic CF-W8 で内蔵無線LANを利用していますが、時々接続開始時に、
NetworkManagerアプレットが接続中の表示(ぐるぐる回るようなアニメーション
中)、急に回転がゆっくりになるとともに、システムがものすごく重くなり、キー
ボードやマウスの操作ができなくなる、という現象が起きています。この際、
以下のようなエラーが messages に出ています。

Jun 15 07:41:00 localhost kernel: iwlagn: Microcode SW error detected.  Restarting 0x82000000.
Jun 15 07:41:00 localhost kernel: iwlagn: Error setting new RXON (-5)

こうなると、再起動以外する以外に回復しなくなるようです。

システムの情報は以下のようになります。もし、原因や対策など、何かわかる
方がいらしたら情報をいただけるとありがたいです。
