LinuxがインストールされているT440は、ハードウェアの問題により停止することがあります。

私はLenovo T440sでLinux 4.9.0-16-amd64でDebian 9を実行しています。これは最近まで安定していましたが、1日に数回停止し始めました。まだアップグレードが行われていないため、ハードウェアによって中断が発生したと思われます。

/var/log/syslogに次のエラーがあります（すぐに中断されない）。

私は失敗を引き起こさずに数時間、memtest、memtest86+、ストレス-ng（cpu、hdd、vmストレス要因）を実行してきました。取引所を終了すると、ほぼ一日の状況が安定していた。こういうわけで、そしてsmartctl -t short まったく行われていないようで、交換用SSDを注文しました。上記の失敗が発生した直後です。私はYouTubeの視聴中にすべてのクラッシュが発生したと思います（しかしそれほど多くはありません）。 glxgearsは欠陥を引き起こさない。

この問題の原因と診断方法に関するアイデアはありますか？

答え1

HDDまたはSSDがあるかどうかを指定していませんが、ディスクの短いテストを試みるのではなく、次のようにして累積SMARTエラー数の要約を表示できます。

sudo smartctl -A /dev/sda

Reallocation_Sector_Ctのゼロ以外の「元の値」は特に懸念されます。

多くの指標では、「高齢」または「事前障害」が発生したと主張していますが、これは明らかに完全に正常な現象です。

答え2

これはメモリ不足によるi915ドライバの問題であることがわかりました。これはLinux 4.19.0にアップグレードすることで解決されました。何ヶ月前に、なぜそのようなことが起こらなかったのかわかりません。これにより、ソフトウェアの問題に対する考えを完全に放棄することになりました。

答え3

私は同じか非常に似た問題に直面しています。 Thinkpad T470/i5-7200Uは、長年にわたりカーネル4.9.0を搭載したDebian 9を使用してきました。少なくとも昨年の4.9.0-14と4.9.0-15は大丈夫でした（最初の試みで時々一時停止できない場合を除き）。最近メモリをアップグレードしました。ケースを開いて（どこでも問題が発生する可能性があります）、4.9.0-16にアップグレードしてください。その後、1日に数回、さまざまなカーネルエラーが発生し、アプリケーションがシャットダウンされるか、システム全体がハングします。システムを停止することもほとんど不可能です。エラーは次のとおりです。

私の最初の考えは同じでした。ハードウェアの破損、両方のRAMモジュールはテストなどでした。その後、USBでDebian 11をテストしましたが、まったく問題はありませんでした。これで4.9.0-14に戻り、カーネルに問題はありません。したがって、バージョン4.9.0-16-amd64には（少なくとも）いくつかのIntel CPUの内部問題があるようです。
