カーネルの一時停止が速すぎるため、再開時に一時停止タスクが続行する

問題はまだここにあり、どれだけ多くの研究を行ったとしても（大抵は以前の研究を繰り返す）、解決策は近づきません。別のユーザーが本日同じ問題を報告しました： スリープモードではバッテリーが非常に速く消耗します

簡単に言えば、私のjournalctl -xeログを見ることができます：

この質問が最初に投稿されたとき、14.04から16.04にアップグレードされたラップトップがありました。それ以来、16.04フレッシュインストールの新しいラップトップを使用しています。問題はまだ残っています：

2月24日の午後11時30分にシステムが一時停止し、2月25日の午前7時40分に再開したことに注目してください。再開すると、システムはすぐに「スリープ」状態になり、その後「ウェイクアップ」します。

バックグラウンド

注：Ubuntu 16.04では、バッテリーとプラグインの両方で電源設定のふたを閉じるを「サスペンド」に設定します。

/etc/systemd/logind.conf内で、デフォルトの「無視」がHandleLidSwitch=suspendおよびHandleLidSwitchDocked=suspendに変更されました。 HDMI外付けテレビが接続されており、これらのオプション（またはUbuntuの電源設定）のいずれかが「無視」または「何もしない」に設定されている場合、ふたを閉じてもテレビが空になるとシステムは動作し続けます。 Ubuntu 14.04（systemdなし）で、ふたを閉じるとサスペンドが正常に機能しました。

Acpi-events、pm-utils、gnome-???には多くの歴史的な変更がありました。おそらくdbus-???。また、フリーズとメモリのさまざまなサスペンド方法を試しています。

正直なところ、試したすべてのことを思い出すことはできませんが、太陽の下ですべてを検索したようです。

/ var/log/syslogの関連コンテンツ

/var/log/syslogを午前5時5分に見ると、システムは（systemdによって）中断されました。午後4時46分（16時46分）にsystemdが再開しましたが、カーネルはラップトップをスリープ状態にし、すぐにウェイクアップしました。 「親CPUはスリープしないでください」などの奇妙なメッセージがたくさんあります。

私の懸念は、この質問が最初に2016年10月に投稿されてから6か月後に他のものが壊れ始めていることです。私はr8169ドライバーをr8168にダウングレードしましたが、それは助けにはなりませんでした。私はネットワークの再起動をセットアップしましたが、それは物事を助けていませんでした。確かに時々DNSが失われます。

関連する/var/log/syslogは次のとおりです。

これは正常ですか？ （リッドクローズは、systemdがより速くサスペンドし、タスクが少なくなることを除いて同じことを行います）。

私が見つけることができるすべての情報を確認した後、Asus、Dell、HP、Lenovoなどを含む多くのシステムに影響を与えている このカーネルバグ の影響を受けているという結論に達しました。さらなる活動が発生しない場合、47日間で期限切れとマークされ、非常に暑く、バグヒートスコアで412を記録し、現時点で86人に影響を与えていると報告されています。それをサブスクライブし、カーネル関連の情報を提供することをお勧めします。この情報を使用して、問題を明確にし、開発者が問題を解決できるようにします。

可能性のある回避策は、注記 here および確認済み here のようにカーネル4.4.8にアップグレード/復帰することですおよび ここ

reverse bisect the kernel の作業が要求されましたが、バグは現在有効期限が切れているため、開発者はこの動作の根本原因を特定するのに必要なすべての支援を得られなかったようです。バグレポートを熟読することでわかるように、この問題はカーネル4.4.0で発生し、4.4.8で解決され、その後4.5.2頃に再び現れましたが、確信があるとは言いません。

別のカーネルアップグレードの回避策が報告されました here .

リポジトリからカーネルを使用している場合、ターミナルからubuntu-bug linuxを起動して、カーネル/問題に関する特定の情報を提供する新しいバグレポートを作成すると役立ちます。

異常な実行を犯人として除外することもできます。次のようにCPU0以外をすべて無効にすることで、これを達成できるはずです。

for x in /sys/devices/system/cpu/cpu*/online; do
  echo 0 >"$x"
done

この情報 は、この問題の根本原因を追跡するのに役立つこともあります。

これは、dmesgに表示される特定の問題です。

PM: Preparing system for sleep (mem)
[...]
PM: Suspending system (mem)

最初にしようとする：

Sudo -H gedit /etc/default/grub

次の行を設定します。

GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor"

この行に以前存在していた他のパラメーターは、変更しないままにすることができます。

変更を有効にするには、次を実行します：

Sudo update-grub

さらに、apt-daily.serviceに問題があるというレポートがあります。これは、ブート時に更新サービスが実行されるため、すべてが無期限に実行され、終了できません。

サービスを無効にしてみてください：

Sudo apt-systemctl disable daily.service # disable run when system boot

私にとって合理的に機能した別の回避策：

Sudo -H gedit /etc/systemd/system.conf

次の行のコメントを外し、設定を、ロードシステムを引き続き許可する値に変更します。

# DefaultTimeoutStartSec = 90s
DefaultTimeoutStartSec = 10s
# DefaultTimeoutStopSec = 90s
DefaultTimeoutStopSec = 10s

調整によって負荷障害が発生しない場合はdmesgに注意し、必要に応じて値を調整します。
