最近のアップデートの後、私のラップトップは起動後数時間以内にランダムにクラッシュが発生し始めました。競合が発生すると、最後の画像がモニターに残りますが、コンピュータが完全に応答しなくなります（番号ロックインジケータは更新されません）。私はOpensuse Tumbleweed、カーネル5.12.2-1、Nvidiaドライバ460.73.01、Quadro M620モバイルGPU、i7-7700HQを含むThinkpad P71を使用しています。
無関係な質問に対して、ネットワークインタフェースは数秒ごとに絶えず上がります。競合が発生する開始では、ネットワークインターフェイス例外に関連するエントリを除いて、競合が発生する数分の間、jourenctlエントリはありません。 NetworkManagerが管理する公式ドッキングステーションを介して内部イーサネットカードを使用します。以下は、衝突前のJournalctlの例です。数時間ログで同じ内容が繰り返されることを確認してください。

他の場所に聞いたら教えてください。 RAMテストをしてみましたが、このコンピュータを1年以上使用してきたので、これが知られているcstate問題のあるCPUの1つだとは思いません。クラッシュが発生するのに2〜20時間かかったため、トラブルシューティングは苦労しましたが、試す必要がある他のものがあるかどうかを知っていました。
答え1
先週も同様のことを見たことがあります。これはkernel-default-5.12.13-1およびNvidiaドライバ460.84で発生する可能性がありますが、インストール直後には発生しないため、他のアップデート（プラズマ、クロムなど）に関連する可能性があります。カーネルベース5.13.0-1.1で引き続き発生します。かなり長い間、安定して実行されてきたデスクトップでこれが3回発生しました。
Chromeは数年前に同様のことを経験しました。 Google chrome-beta 92.0.4515.80-1でGPUを高速化するための高度なオプションをオフにしました。これまで私は別の封じ込めを見たことがありません。しかし、今はカーネルのデフォルト値5.13.0-1.2とChrome Beta 92.0.4515.93-1も使用しているので、状況が変わることがあります。
私は通常nvidiaフォーラムでこの質問をします（過去にはnvidiaサポートスタッフが非常に役に立ったと聞きました）。しかし、ログや/var/log/Xorg.0.logでパターンや興味深いものを見るまでこれを躊躇します。最近の衝突による/var/log/Xorg.0.logがある場合は、ここに手がかりがあるかもしれません。
