起動後のサーバーカーネルパニック、ログの作成方法がわからない

新品のデュアルCPUサーバーを受け取ったばかりですが、起動後すぐにカーネルパニックでクラッシュし続けます。これは、アイドル状態のOSセットアップ中にも発生しました。 OSをインストールし、mcelogが何が起こっているのかを理解できるようにすることができましたが、出力をどうするかはわかりません。オンラインで読んだことで、これはソケット（1）の1つでDIMMに欠陥があるのではないかと思いましたが、いくつかのパスでmemtestを実行しましたが、エラーは見つかりませんでした。代わりに、これがソフトウェアの問題である可能性はありますか？私はすでに2つのOSを試しましたが、Debian/ProxmoxではCentOSよりもはるかに一般的でしたが、両方で同じことが起こりました。

サーバーの仕様：

デュアルIntel8コアXeonE5-2620v4

2 x DIMM 32GB DDR4 2400MHz RECC DDR4

MB SuperMicro X10DRL-i

MemtestまたはOSのインストール中に35ºCを超えることはなかったため、CPUサーマルではありません。また、CPUがクラッシュする前に、CPUでいくつかのショートベンチマークを実行することができ、温度は問題ありませんでした。

ここで何が起こっているのかをどうやって理解できますか？発生する前に数分間サーバーにアクセスできます。すでにvmcoreダンプをダウンロードしていますが、どうすればよいかわかりません。

起動してからクラッシュしてから50秒後のmceログは次のとおりです。

返信が遅いことは知っていますが、完全に忘れてしまいました。 CPUが正しく配置されていないか、出荷中に緩んでいた可能性があります。少なくとも、ベンダーは物を交換しなかったと言っているので、それは私に言ったことです。

彼らがそれを返送した後、すべてが機能していました。
