こんにちは。 マシンにUSB2.0の外付けハードディスクを使用した直後から topコマンドのinterruptの所が15%（普段は1%未満）ほどに上昇しました。 http://svnweb.freebsd.org/base/head/sys/dev/usb/controller/xhci.c?view=log#rev245132 これをダウンロードしてカーネルを作りなおせばいいのかなと思いましたが、 C言語など分からないもので、カーネルの設定ファイルの 「device xhci # XHCI PCI->USB interface (USB 3.0)」 をコメントアウトし、カーネルを作りなおして対処しました。 その結果、CPU使用率やload averagesは以前の状態に戻りました。 これはどう対処するのが良いのでしょうか。 以下マシンの環境となります よろしくお願い致します。 マザーボード -> http://www.asus.com/Motherboards/P8B75M/#specifications # dmesg Copyright (c) 1992-2012 The FreeBSD Project.
