我刚刚安装了 17.10，apt 和 Firefox 都出现了段错误。这两个问题可能毫无关联，但我还没能找出原因。
对于 apt，我得到的症状让我认为是这样的：https://ubuntuforums.org/showthread.php?t=773787，但是当我尝试从该线程修复时，什么都没有改变。
对于 Firefox，标签页每 5-10 秒就会崩溃一次，导致浏览器无法使用。
这里有dmesg我遇到的错误：

等等。
我该怎么做才能尝试找出这个问题的根本原因？

感谢@CharlesGreen 的回答：
原来是内存模块坏了。以后读到这篇文章的人都应该考虑在重新安装 RAM 后运行内存诊断程序。然后使用取出并移动的模块组合进行测试，以确定是单个模块、一个插槽还是多个插槽存在问题。
