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？

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。
