首先我要说的是，这篇文章与另一个帖子这是一年前制定的，但具体内容已经改变，我想再确认一下我是否应该提交错误报告，或者我是否应该先做些其他事情来尝试修复我的内核安装。
我更新了我的电脑，当我启动最新的内核时，我看到了紫色屏幕。当我尝试在该内核中运行恢复模式时，我看到了内核恐慌输出。
我尝试使用以下方法重新安装最新的 3.19 内核这里给出的建议。其输出如下（如果有任何有用的信息）。

现在我可以继续启动旧内核，但我想通过执行以下命令升级到 4.2：
sudo apt-get install --install-recommends \
linux-generic-lts-wily
这在我正在重新设置的桌面上起作用了，我想看看它是否能起作用。有趣的是HWE 文档声明这对于服务器来说是可以的，但没有提到对于桌面来说，这就是我一直推迟的原因。
2016 年 2 月 11 日更新
我尝试安装 4.2 内核，但遇到了同样的问题，所以我认为这与内核无关。我希望得到一些诊断此问题的建议。否则，我似乎需要执行完全重新安装。

Ubuntu 官方内核中的内核恐慌几乎总是应该报告给Launchpad 上的内核错误跟踪器，如果有必要，他们可能会将问题上报给上游的错误跟踪器 — — 当然，除非你发现类似的现有报告。
我相信对于你的情况也是如此。
