使用 syslog 诊断崩溃

  • 772

这更像是对经验丰富的眼球的要求，而不是连贯的问题。

我在图书馆工作，我们使用一台来自中国的 100 美元的小型英特尔凌动计算机在支持 HDMI 的电视上播放循环的 LibreOffice Impress 幻灯片。

今晚我注意到，无论我看了多长时间，幻灯片都没有前进。尝试通过 SSH 登录，没有任何反应。（我们在没有连接鼠标或键盘的情况下运行计算机，只使用 SSH 和 VNC。）

我正在运行 Ubuntu 18.04，但它可能使用比标准更新的内核。这样做的一些原因：我在通过 HDMI 输出声音时遇到问题，并且在视频播放方面也遇到问题（尤其是在 LibreOffice Impress 演示文稿中）。现在我们只需要一个无声的幻灯片，所以如果我必须回滚内核（如果可能的话），这可能不是世界末日。

我将大约 300KB 的 /var/log/syslog.1 日志放在了 Pastebin 中： https ://pastebin.com/PiU8MnTX （事情在 18 年 11 月 16:38 开始。）

但这里是最后几个条目：

然后是一大堆有趣的\00\00，可能是从哪里崩溃或者我按住电源按钮所以它会关闭。

***SYSTEM FREEZE***

    错误报告的标题是：

    • [v2,4/5] i2c：designware-baytrail：强制 CPU 进入 C1 状态，同时保持 punit 信号量

    解决方法将我们引向 Linux-Land / Ubuntu-Utopia 中这个臭名昭著的线程：

    最好的办法是使用以下命令更新 grub 命令行 ( sudo -H gedit /etc/default/grub)：

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=1"

    然后运行：

    sudo update-grub
