休止状態後のXFSメモリ内破損

ソフトウェアraid-1に存在するXFSファイルシステムで、以下のエラーが絶えず発生し、その後、3-disk raid-5に変換されました。エラーは、通常、休止状態の後、通常はすぐに、または数分後に発生します。dmesg伝えます（完全なdmesg出力はこちら：http : //bpaste.net/show/130895/）：

カーネルバージョンは3.10.7で、3.8.13でも同じエラーが発生しました。md1はXFSファイルシステムに使用される唯一のRAIDデバイスではないことに注意してください：私はRAID1（SSD + HDD）も保持しています。

i915カードをお持ちの場合は、カーネルを更新してみてください。これらのカードのKMSにより、休止状態/再開時にメモリが破損するという報告がいくつかありました。

i915.modeset = 0でテストして、問題が消えるかどうかを確認できます。もし消えた場合は、おそらく同じ問題であり、最近のカーネルではすでに修正されているはずです。

i915をお持ちでない場合、何が問題なのかは不明です。BIOS/電源設定を試してみて、Xなしで休止状態にし、別のグラフィックカード関連の破損をテストし、memtest86を実行して実際のメモリの問題を確認しますカーネル...そして、問題が再現可能な場合、おそらくディストリビューション/カーネルのバグを開きます。

休止状態から再開した後、3.16.5で同様のコールトレースを見てきました。ext4に切り替えましたが、問題はありませんでした。

私のセットアップでは、xfs roofsとファイルスワップ（スワップパーティションではない）を使用しました。サスペンドとハイバネートは正常に機能し、リバウンドはハイバネートからの一部のコールトレースを除き、両方とも正常に機能しました。

システムは、中程度のファイル操作が始まるまで半使用可能です。リトマステストを実行するには：

# tail -f /var/log/messages

その後、休止状態になります。再開後、システムは応答しなくなります。ext4では、コールトレースが表示されず、システムは正常に見えます。

私はこれを見たときにxfsでいくつかの問題を疑っていました：
