Ubuntu 15.04が6〜10秒ごとに1秒間フリーズし、kern.logのPCI / Radeon関連メッセージ

今夜、ラップトップのAcer Aspire TimelineX 4820TGにXubuntu 15.04を新規インストールしました。以前は14.04 LTSを実行していましたが、すべて順調でした。保存するものがあまりなかったので、システムをきれいにするために、完全なアンインストールと再インストールを行いました。

残念ながら、最初の起動以降、定期的にフリーズします。 フリーズは6〜10秒ごとに発生し、約1秒続きます。フリーズ中にマウスとキーボードが応答しないため、すべてのシステムが見えます。それは非常に迷惑です。

さらに、フリーズが発生するたびにファンの速度が上がるのを聞くことができます。シャットダウン時にシステムがハングします(電源ボタンを長押ししなければなりませんでした)。

everyフリーズ中に、/var/log/kern.logのこれらの正確な行が出力されることに気付きました。

同様のメッセージを検索すると、いくつかのヒントに出会い、ブートオプションpci=noacpiを最初に試し、後でnoacpiを試しました。 彼らは問題を解決しますが、残念ながら両方ともUSBマウスが動作しません(他の外部USBデバイスについてはテストしませんでした)。

ここで問題は何ですか? 12.04が問題なく動作するのはなぜですか?マウスやその他のUSBデバイスを機能させたまま、どうすれば解決できますか?

ありがとうございました。


UPDATE:さらに調査した結果、15.04のアップデートされたカーネルでは壊れているように見えるラップトップのダブルスイッチング可能なグラフィックに関連していることがわかりました。

radeon.runpm=0ブートオプションで解決しましたが、ディスクリートグラフィックカードの動的なオン/オフが機能しないため、システムの温度が上がり、バッテリーの寿命が短くなります。

XorgとLinuxカーネルBugzillaで問題を報告した後、カーネルパッチのテストに招待されました( これはパッチですこのバグ に投稿されました)。

パッチを当てたカーネルをコンパイルしてインストールすると、問題はなくなり、ディスクリートグラフィックカードの動的なオン/オフが再び機能します。

正しい方向を示してくれたカーネル開発者に感謝しなければなりませんが、残念ながらこれは迅速で簡単な解決策ではありません。次のカーネルリリースですぐに修正を出荷できることを願っています。

Ubuntu 15.04でも同じ問題が発生しました。 psensorsを削除して解決しました

Sudo apt-get remove psensors
