為了解掉一些問題, 不得不把 kernel 升級到 3.2, 參考了同事的作法及網路上的作法, 下面是我的紀錄

需要使用 kdump 及 scst, 所以參考這兩份來打 patch 及做開關 option 的動作
http://www.mjmwired.net/kernel/Documentation/kdump/

flavour 的名字千萬不要有 "-" 或是 "." 都會造成最後會有 error, 如果看到類似以下的問題, 就是這個原因

3/12 補:
http://www.ubuntuupdates.org/package/core/precise/main/base/linux-source-3.2.0
在 3.2.0-18.28 時 apparmor 有大改動, 其中拿掉了 SECURITY_APPARMOR_COMPAT_24, 這個造成安裝某些軟體時會出現 "Kernel needs AppArmor 2.4 compatibility patch." 這樣的 warning, 由於不知道會有什麼影響, 於是最後決定用 3.2.0-17.27
