ACPI Errorについて
自作PCで自宅サーバを構築中です。
OSはCentOS6.2です。
/etc/log/messagesでログの確認を行うと、ACPI Errorのログが出力されます。
以下は、ログの一部です。

ハードウェア、ACPIに詳しくないのでログの意味がよくわかりません・・・。
ログの解釈と解決方法(ACPI Errorを出力しなくする)を教えてください。。。
よろしくお願いします。
お礼
お答え頂きありがとうございます。これは知りませんでした、参考になりました。
補足
PCIスロットは2本空いています。またAGPスロットにはAGP2倍対応のカードを挿してますが、なぜか等倍動作になってます。
