以下は、Thunderbolt3を介してドックに接続されたノートブックのシステムと問題の概要です。ドックは、2つのモニターと、イーサネット、USBオーディオなどのような他のデバイスを提供します。
問題：ノートブックカバーを上に置くと、ドッキングステーションがあってもすべてがうまく機能しますが、Wi-Fiネットワーク（接続）に接続するまでのみ機能します。接続を確立すると、Dockが取り出され（接続が切断され）、システムが停止します。ふたサスペンションをロックしようとしました。結果は同じですが、一時停止はありません。 Wi-Fiがオンになっているか、検索中の場合は正常に動作します。しかし、今奇妙な部分があります。ふたが開いていると、Wi-Fi経由で正しく動作できます。

システムはTB16ドック付きのDell XPS 9350です。 1週間前にDockのファームウェアを更新して、MSTディスプレイポートファームウェアのいくつかの問題を解決しました。カーネル5.15.0-71-generic(buildd@lcy02-amd64-044)も先週5.15.0-69で更新されました。今回のアップデート以前は正常に動作しました。
この問題をどこで解決し始めることができるのかご存知ですか？このメッセージのため、これがPCI IO割り当てに関連している可能性があると思いました。
