内核暂停太快，恢复后继续暂停任务
10月21/2018更新
问题仍然存在，无论我做了多少研究（大多数重复以前的研究），解决方案都不会更接近。 另一位用户今天报告了同样的问题： 睡眠模式非常快地耗尽电池
简而言之，您可以看到我的journalctl -xe日志：

16:13:14系统恢复，但暂停继续冻结任务

当这个问题最初发布时，我有一台笔记本电脑，从14.04升级到16.04。 从那时起，我有一台全新16.04安装的新笔记本电脑。 问题仍然存在：

注意系统如何在2月24日晚上11:30暂停，然后在2月25日上午7:40恢复。 恢复系统后立即进入“睡眠”然后“醒来”。
背景
注意：在Ubuntu 16.04电源设置中，电池和插入电源的“关闭”设置为“暂停”。
在/etc/systemd/logind.conf ，默认值“ignore”更改为HandleLidSwitch=suspend和HandleLidSwitchDocked=suspend 。 连接HDMI外部电视的原因是如果这些选项中的任何一个（或Ubuntu电源设置）设置为“忽略”或“什么都不做”，系统会在盖子关闭但电视空白时继续运行。 在Ubuntu 14.04（没有systemd）暂停时，盖子关闭按预期工作。
有很多历史修补的acpi-events，pm-utils，gnome – ??? 可能还有dbus – ??? 还试验了各种冻结和记忆的暂停方法。
老实说，我不记得尝试过的所有不同的东西，但似乎我在阳光下搜索了所有东西。
/ var / log / syslog的相关内容
在凌晨5:05查看/var/log/syslog系统被暂停（由systemd？）。 在下午4:46（16:46），systemd恢复了，但是内核让笔记本电脑进入睡眠状态并立即唤醒。 有很多奇怪的消息，比如“ 父CPU不应该睡觉 ”。
我担心的是，在这个问题最初发布于2016年10月之后的6个月内，其他事情开始破裂。例如，以太网在从挂起唤醒和wifi接管时没有重新连接。 我已经将r8169驱动程序降级为r8168，但这并没有帮助。 我已经设置了网络重启，但这没有帮助，事实上有时DNS会丢失。
这是相关的/var/log/syslog ：

这是正常的吗？ （注意lid-close做同样的事情，除了systemd更快地挂起并执行更少的任务）。
这是dmesg中出现的特定问题：
PM: Preparing system for sleep (mem) [...] PM: Suspending system (mem)
最初尝试做：
sudo -H gedit /etc/default/grub
并设置行：
GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor"
之前存在于该行中的其他参数可以保持不变，即，有时仅指示添加该参数。
要使更改生效，请运行：
sudo update-grub
另外还有apt-daily.service问题的报告，这是更新服务在启动时运行，这使得它无限期地运行，无法完成。
尝试禁用该服务：
sudo apt-systemctl disable daily.service # disable run when system boot
对我合理的另一种解决方法：
sudo -H gedit /etc/systemd/system.conf
更改以下行，取消注释并设置为仍允许加载系统的值：
# DefaultTimeoutStartSec = 90s DefaultTimeoutStartSec = 10s # DefaultTimeoutStopSec = 90s DefaultTimeoutStopSec = 10s
如果调整未产生负载故障，请注意dmesg，并在适当的情况下调整该值。
在查看了我能找到的所有信息之后，我得出的结论是你受到了这个内核bug的影响。 这已经影响了包括华硕，戴尔，惠普，联想等在内的众多系统。如果没有进一步的活动，这个将在47天内到期的错误非常火爆，在臭氧热得分上得分为412，据报道影响86人们此刻。 我建议您订阅它并提供任何内核相关信息，以帮助澄清问题，以便它保持开放状态，开发人员可以压缩它。
一个可能的解决方法是升级/恢复到内核4.4.8，如此处所述并在此处和此处确认。
已经要求工作反向平分内核但该错误当前未分配，因此看起来开发人员可以使用他们可以获得的所有帮助来确定哪个最近的内核是第一个显示此行为的内核。 我可以通过仔细阅读错误报告来看出这个问题出现在内核4.4.0中，在4.4.8中得到解决，然后在4.5.2左右重新出现，但我不会声称是确定的。
此处报告了另一种可能的内核升级变通方法，尽管我还没有找到确认。
如果您使用存储库中的内核，如果您从终端启动ubuntu-bug linux以创建新的错误报告，提供有关您的内核/问题的特定信息，则可能会有所帮助。
