Ubuntu 16.04 (および 17.04) がランダムにフリーズする

私たちは以下の仕様のプレビルドマシンを注文し、SSD に Ubuntu 17.04 をインストールしました。Ubuntu は 4 つの異なる時点でランダムにフリーズしました (Python 用の Anaconda のインストール中を含む)。私たちは同じ SSD ドライブで 16.04 に移行することにしました (私たちは日常の仕事でこの OS によく慣れていたため)。しかし、問題は解決しませんでした。

これは、フリーズが発生した時刻に関連付けられた syslog の出力です。

答え1

結局、Linux を再インストールして、テスト済みの新しいバージョンではなく NVIDIA ドライバーの 340 バージョンを有効にする必要がありましたが、今のところ 24 時間フリーズはありません。スタンバイからの復帰も機能します。この状態が続くことを願っています。 –フォロー
