Ubuntu 崩溃 - 如何读取日志文件

Question

Ubuntu 崩溃 - 如何读取日志文件

几天前，笔记本电脑决定在没有相关原因的情况下关闭。从今天开始，它随机崩溃，没有任何解释。

这是我（正确？）从上次崩溃时的日志文件中过滤出来的内容，但我不知道这意味着什么。当时有几个进程在运行：chrome 和 firefox 上的许多网页，带有 WindowsXP 和 clamscan 服务的虚拟机。

问题的根本原因是什么？另外，您认为我必须激活该apport服务才能获得更多信息吗？

虽然前一个包含我认为与崩溃相关的所有日志（检查时间戳），但这些是完整日志的链接

崩溃发生在11 月 4 日 10:53:56（实际上，大约一小时前又发生了一次崩溃，但我不知道正确的时间戳，因为我不在笔记本电脑附近）。

奇怪的事情：你有没有注意到有一行与之前的时间戳不同？我是说这个

好吧，我再次尝试运行 a clamscan，这次只在我的home目录中。然而，在某个时候，核心温度超过 98°C，所以我停止了这个过程。我尝试以clamscan详细模式再次运行以查看特定文件是否存在错误。在某个时候，核心温度超过 90°C，但这次桌面关闭，然后计算机停止。另外，我有一段时间无法重新启动它（直到我认为它再次冷却）。所以，我认为问题与高核心温度有关。一定，clamscan笔记本电脑冻结了 4 次（唯一一次没有冻结是因为我手动强制停止进程）。对于之前的崩溃，也许某个进程在某个时间点开始预热内核；但是，我不知道是什么过程。FWIW，这些是在事件崩溃时过滤的日志文件。系统日志 kern.log 的strange格局又发生了。有什么建议吗？
