如何下载和使用除默认安装的内核之外的任何其他内核
假设我使用的是Ubuntu 12.04（LTS），它使用3.5.0-37内核。
如果我想使用3.9.6内核，我该如何使用它？ 我不想升级到13.04
我是否必须手动下载此内核，编译它并创建它的initrd，或者我可以通过启用某些存储库使用apt-get install来获取它吗？
请帮忙。
向后移植的内核在12.04中可用，请参阅以下问题以获取有关如何启用它们的说明：
- Ubuntu点发布会包含一个新的Linux内核吗？
- 12.04.2中的Quantal backported内核？ 那里发生了什么？
- 如何将12.04.2内核和HWE升级到raring？
另一种方法是构建自己的内核或使用vanilla内核： 如何获取和安装未修改的内核？
如果你知道一些基本的bash脚本，从下面的脚本（即使它们看起来很长很容易理解）你可以看到如何下载和使用任何其他内核。
