[plamo:29080] Plamo-4.5のおかげ。

[名倉昭一]

 　名倉@手元ではじわりじわりとPlamo-4.2xからPlamo-4.5に世代交代しつつある です。

　　Plamo-4.22ベースのファイルサーバーをlinux-2.6.23.17からlinux-2.6.24.4にしましたが
　　ネットにつながらない感じ。

　　dmesg見てみたら

　 な感じでした。どうもmodprobe r8169あたりがおかしいみたい?
   linux-2.6.23.17で起動すると普通に動きました。
　 ためしにPlamo-4.5(お勧めm)に入れなおし,まずlinux-2.6.23.17を入れlinux-2.6.24.4に入れ代えて見たが
   問題ないようです。

　 連続運転ではありませんが数日間動いています。

　　CPU   　Intel Celeron (Mendocino) 500MHz
