[Armadillo:01089] Armadillo-9 で irq49: nobody cared

吉村と申します。

Armadillo-9の内蔵kernelから起動後，
ハギワラシスコムのCF Zpro 512MBをfdiskすると以下の情報がコンソール
に出ます。
このCFにアクセスするとこの状況が頻発します。　しかし，実際の読み書
きは正常に行われているようで，CF上にDebianを構成して，CFのkernelか
らbootも可能です。　CFからbootしても同様のメッセージが出ます。

kernel2.6, romfsは改変無しに利用しております。
kernel2.4でも起こるかは未確認です。
どう対応したらよいのかご教授願います。
