Ubuntu 14.04 LTS无法以内核崩溃启动

这可能是由较新内核反向移植的修复程序和功能引起的。

在GRUB菜单中，选择Ubuntu的Advanced选项，选择最后一个可用的内核（不是恢复模式）。

现在你可以：

• 删除新内核并继续使用旧内核，使您的系统容易受到旧内核的攻击
• 安装较新的内核，并为此修复了这些问题

Easiest way to install new kernel is to download it from kernel.ubuntu.com and install it using dpkg.

First, select the version you want (preferably the newest non-rc one, utopic kernels will work for 14.04 too), then download 3 files:

• linux-headers-x.xx.x-xxxxxx-generic_x.xx.x-xxxxxx.xxxxxxxxxxxxx_architecture.deb
• linux-headers-x.xx.x-xxxxxx_x.xx.x-xxxxxx.xxxxxxxxxxxx_all.deb
• linux-image-x.xx.x-xxxxxx-generic_x.xx.x-xxxxxx.xxxxxxxxxxxx_architecture.deb

Replace architecture with i386 if you use 32-bit Ubuntu, or amd64 if you use 64-bit one (it has nothing to do with CPU manufacturer!).

Move these files to separate directory, open your terminal, cd to that directory and then run this command:

sudo dpkg -i *.deb

When dpkg finishes, you can reboot, and ensure that you are running the kernel you've installed:

uname -a
Linux m132 x.xx.x #1 SMP Tue Jun 10 00:45:23 CEST 2014 x86_64 x86_64 x86_64 GNU/Linux

Remember, you'll have to update kernel manually now, because Software Updates will only install 3.13 patches, as the kernel version never changes after Ubuntu release.

If it still doesn't work, uninstall the kernel you've installed with

sudo apt-get purge linux-headers-3.13.0-24 linux-headers-3.13.0-24-generic linux-image-3.13.0-24-generic
sudo apt-get purge linux-image-extra-3.13.0-24-generic 

Replace 3.13.0-24 with version you want to uninstall (or press Tab key to list installed ones). Second command may throw an error as there's no linux-image-extra for some kernels.

PS: Please, follow these instructions to make a bug report for that faulty kernel, so they can fix it for others :)
