ArchLinux-システムがハングして応答しなくなる
特定のラップトップで数週間問題が発生しています。同じOSとアップデートを備えた別のものは正常に実行されています（したがって、これはハードウェアの問題だと思います）。多くのIOアクティビティ（ファイルのコピーやCPUを集中的に使用するタスクなど）を実行すると、システムがハングしているように見えます。コンピュータを再起動しない限り、システムは元に戻っていないようです。当初は、Firefoxまたはクロム、次にFlashplayerの問題だと思っていましたが、Firefoxまたはクロムを強制終了すると、コンピューターは再び応答しますが、最終的には再び応答しなくなります。
私はこれをdmesgで見ます：

おそらくメモリが不良であるようです。また、ハードドライブがプリフェイル状態にあることを示しています。それが貢献するかどうかはわかりません（これらのプログラムはすべてすでにメモリにあるはずなので、私はそれを疑っています）。
メモリテストmemtest86を実行しましたが、エラーは見つかりませんでした。私の記憶は悪いですか、それともここで他に何が起こっているのですか？私のシステムで何が壊れているのか、そしてそれを修正する方法について何かアイデアがあれば知りたいです。
最近、nvidiaとATIシステムの両方でFedoraでこれが発生したという報告を見たので、これはgnome-session/gnome-Shellのバグのようです。この問題は3.2アップグレードの頃に発生し始めたばかりであり、このOSとバージョンを実行している他のシステムでも発生しないのは独特です。
