[plamo:18319] 起動時にLANカードでカーネルパニック

[Itsuki Minobe]

初めまして。美濃部と申します。

今、PC9821Nr13/D10でPlamo-2.1を動かしているのですが、さっきカーネルの再構築
をしてから起動時にLANカードを挿しっぱなしにしておくとカーネルパニックを起こ
すようになりました。
最初は起動時のメッセージがおかしいなと思って、ちょうどLANカードのところで止
まっていたからLANカードを抜いたのですが、そうすると「Kernel panic」と表示さ
れ、完全に止まります。
LANカードはMELCOのLPC2-T、pcmciaバージョン3.1.24でさすだけで認識していたので
すが。
抜いておくと普通に起動します。そのあとLANカードを挿すと、少し多めにメッセー
ジが表示されてから普通コマンドが入るようになります。
つい何週間前にはじめたところで、理由もさっぱりわかりません。誰か教えてくださ
い。
dmesgをするとこう表示されます。
