PS / 2キーが押されるまで起動プロセスは停止しますか？

Mini-ITXマザーボード上で実行されているGentoolinux3.6.6に基づく組み込み製品に取り組んでいます。マザーボードの切り替え（JetwayNF9D-2550からAdvantechEIMB-214へ）を検討しており、既存のSATA開発ドライブを新しいマザーボードから起動しようとしていることをテストしています。

試してみると、次の2つのメッセージが表示されるまで、システムはBIOSとGRUBを介して起動します。

[0.588839] BIOS EDD facility v0.16 2004-Jun-25, 0 devices found
[0.588902] EDD information not available.

その後、システムはハングし、それ以上進みません。 BIOS設定（AHCIとIDE、USB、SATAの有効化/無効化など）とブートパラメーター（edd=off、verbose）を何度も試しましたが、役に立ちませんでした。

これが私が見つけた1つの助けです。 PS/2キーボードを接続し、起動プロセスが通常のハングポイントに達するまで待つと、ほとんどの場合、キーを押すと、起動プロセスがさらに1〜2ステップ進みます。

キーを押すたびに（いくつかの操作が速すぎない限り）、1つ以上の新しいログ行が表示されます。各ログ行の左側のタイムスタンプは、合理的に増加し続けます。 10秒待ってからキーを押すと、新しいメッセージのタイムスタンプが前のタイムスタンプより10秒大きくなります。待機時間とキーを押したときに表示されるメッセージの数の間には、ある程度の相関関係があります。待機時間が長くなるほど、より多くのメッセージが表示されます。

どのキーを押すかは問題ではないようです。 SHIFTまたはCAPS-LOCKでも機能します。外部のソフト電源ボタンを押しても機能します！ USBキーボードは何もしません。 PS/2キーボードのみ。また、キーボードが接続されていない場合は、通常の場所でハングします。

これを十分長く続けると、起動プロンプトが表示されてログインできますが、それでもキーを押すまで繰り返しロックされます。

ここで何がうまくいかないのか手がかりはありますか？

私はいくつかの提案を試しましたが、役に立ちませんでした。以下は何も変更しませんでした：

  • カーネルコマンドラインにisapnp_reserve_irq=5を追加する

  • BIOSをデフォルト値に完全にリセット

編集5：

もう1つの証拠：bashコマンドライン（コンソール/ VGAディスプレイ上）を見て、コマンドを入力すると、カーネルからのログメッセージのバーストが表示されることがあります。コールトレースのように見えます。タイムスタンプ情報と命令オフセットを省略して、ここに1つあります。

さまざまなLiveCDから起動しています。結果：

  • GParted 0.14.0-1 Live x86 CD：繰り返し出力されるシェルスクリプトを含め、正常に動作します

  • Ubuntu Desktop 12.04.1 x386：起動しますが、同じ「イベントを待機中」の病気があります。起動プロセス中にキーを繰り返し押す必要がありました。 Xwindowsの起動が終了したら、ターミナルウィンドウを開き、1秒に1回メッセージを出力するシェルスクリプトを作成して、実行しました。各出力行の後で、続行するにはキー（SHIFTなど）を押す必要がありました。興味深いことに、このスクリプトを実行している2つのターミナルウィンドウを開くと、両方がロックされますが、キーを押すと両方が前に進みます。約20分間実行した後、システム全体がロックされました。

  • Gentoo Live DVD livedvd-x86-AMD64-32ul-20140826.iso、x86の起動：すべてが正常に機能しました。

Ubuntu 12.04.1にいる間、私はいくつかのハードウェアレポートを取得することができました。

私はそれがあなたのハードディスクのヘッドまたはMBRに関係しているに違いない、そしてあなたの問題は実際にたくさん起こる。

標準が異なるため、一部のBIOSはMBRより上のアドレスから読み取る可能性があり、問題を引き起こす可能性があります。これを解決するには、partedを使用してみてください。また、一部のW.D.ドライブには不可解なヘッドがあります。

parted -lの出力と初心者向けのgrub.cfgを投稿して、ウィキペディアがMBR（マスターブートレコード）と https://en.wikipedia.org/wiki）について何と言っているかを読むことができますか？/INT_13H それはプロセスに大いに役立つからです。

ハードドライブのメーカーとストレージ容量はどのくらいですか？
