When you are suffering from issues in Linux, upgrading your Kernel can sometimes fix these issues. We earlier saw this to work for users who switched to the Unity desktop in Ubuntu 11.04. Recently, a stable version of the Linux Kernel 3.4 was released. The changes include improved metadata performance with support for metadata blocks larger than 4KB, better recovery tools and error handling, updates for GPU drivers, and more. If you would like to update your Kernel for Ubuntu 12.04 Precise Pangolin, then check out the instructions given below. The complete details regarding the new features of Linux Kernel 3.4 can be seen here.
