私のラップトップにキングストン KC3000過剰なIOの間、NVMe SSDは使用できなくなります。これは私のブートドライブなので、この問題はLinuxをクラッシュさせます。カーネルパラメータを設定しようnvme_core.default_ps_max_latency_us=0としましたが、pcie_aspm=off問題は解決されませんでした。エラー発生時のドライブ温度は61℃で、動作温度は0℃～70℃と明記されているとみなされ、サーマルスロートリングが原因ではないようです。これがハードウェアの問題かソフトウェアのバグなのか、次に何を試すべきかわかりません。

マイコンピュータ（TEAM MP33 PRO）の他のNVMe SSDで同じ書き込みテストを試みましたが、競合はありませんでした。ただし、キャッシュがいっぱいになるとドライブのパフォーマンスが停止します。
研究
Arch Wiki には「APST サポートの中断によるコントローラエラー」セクションがあります。https://wiki.archlinux.org/title/Solid_state_drive/NVMe#Power_Saving_(APST)以前のKingstonドライブと古いカーネルへの言及があります。私のドライブにはファームウェアアップデートがなく、5.19カーネルを実行しています。
また、提案default_ps_max_latency_usとpcie_aspm調整も読みました。
