Ubuntu 16.04 在关机时挂起

Question

我知道还有其他类似的问题，但我会提供有关该问题的更多详细信息。

当我尝试关闭/重新启动时，系统永远挂起。这适用于 Ubuntu 16.04 64 位。它在升级后的 Kubuntu (14.04 » 16.04)、新安装的 Lubuntu 16.04 和活动 CD 上的同一台机器上附加（iso 从硬盘使用 grml-rescue 引导）。

如果我从桌面环境关闭/重新启动，如果我从终端执行它，它就会出现。

该问题不会出现在安装在同一硬盘上的 Ubuntu 14.04 上。

磁盘

我试图在分区上运行 fdisk，但没有发现错误。

查询

我试图将irqpoll参数添加到系统启动

linux /boot/vmlinuz-4.4.0-31-generic root=UUID=c50c612d-813b-4e76-a6d0-92e697658b7a ro irqpoll $vt_handoff

BIOS USB3

有人通过关闭 bios 上的 usb3 legacy 支持来解决，但是我的主板很旧，我的 bios 上没有 usb3 支持

systemctl 和交换

这个答案https://askubuntu.com/a/769953/23130 谈到了 2 个可能的问题：systemctl和swap

sudo swapoff
sudo systemctl reboot

但没有任何主题作品

关机调试

上一个答案指向了一个有趣的 Launchpad 讨论 https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1464917

其中有一段介绍性文字说：

如果您遇到关机挂起，请提交单独的错误报告并按照 /usr/share/doc/systemd/README.Debian.gz 的“调试启动/关机问题​​”部分中描述的调试说明检查是否存在关闭时任何挂起的工作。在救援外壳中捕获“journalctl -b”的屏幕照片可能会有所启发。

所以调试指令说

sudo systemctl enable debug-shell
sudo halt

然后当关机挂起时，你在 VT9CTRL+ALT+F9上有一个控制台，你可以在那里做

systemctl

查找状态为active 的单位

systemctl list-jobs

列出的所有作业都带有 state waiting，唯一带有 state running的upower.service是粗体。

所以我关闭了电脑并重新启动，现在在我已经完成的终端中

sudo systemctl list-jobs

输出是

JOB UNIT           TYPE  STATE  
1341 upower.service start running
1 jobs listed.

所以我试图关闭它并在将来禁用它

sudo systemctl stop upower.service
sudo systemctl disable upower.service
sudo systemctl mask upower.service

然后我再次尝试击落，使用调试控制台

sudo systemctl enable debug-shell
sudo halt

但是关机像往常一样冻结，而且现在我什至无法访问调试外壳。

在没有安静启动grub 选项的情况下启动我可以看到关闭挂在输出线上

Reached target Shutdown

这些是关于关机的系统日志行

这是我的lshw 输出

有人能帮我吗？对我来说难以置信的是，如此严重的错误会影响 LTS。

Answer 1

我想我找到了解决方案。我正在寻找另一个问题的解决方案：lsusb命令永远挂起，所以我找到了这篇文章 https://ubuntuforums.org/showthread.php?t=2301619

然后我想起我的主板上插了一个USB3 PCI卡但没有通电，拔掉它后问题解决了。

希望能帮助到你。
