首先让我说明这篇文章与一年前的另一篇文章非常相似，但它的细节发生了变化，我想仔细检查我是否应该提交错误报告，或者是否还有其他我应该首先尝试修复我的内核安装。

我已经更新了我的电脑，当我启动最新的内核时，我会看到一个紫色的屏幕。当我尝试在该内核中运行恢复模式时，我会看到内核恐慌输出。

我尝试使用此处给出的建议重新安装最新的 3.19 内核。其输出如下（如果有任何有用的信息）。

现在我可以继续从旧内核启动，但我很想通过执行以下命令升级到 4.2：

sudo apt-get install --install-recommends \
linux-generic-lts-wily

这已经在我重新设置的桌面上工作了，我想看看它是否可以工作。有趣的是，HWE 文档声明这对服务器来说没问题，并没有提到桌面，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 内核并遇到同样的问题，所以我认为这与内核无关。我很想得到一些关于诊断这个问题的建议。否则看起来我需要执行完全重新安装。
