Linux Kernel 3.8.3 Released–How To Upgrade In Ubuntu
The Linux Kernel 3.8.3 has just been released and this brief tutorial is going to show you how to easily upgrade to it in Ubuntu. Upgrading your kernel is not recommended as it has the propensity to break stuff. It is recommended to always upgrade the Linux Kernel along with the OS after it has been proven and tested to work with your systems.
With that being said, sometimes upgrading your kernel can fix issues you’re currently experiencing with your computers, and if you just can’t wait for it to be tested and released, go ahead and upgrade.
This is a maintenance release that’s part of the Kernel 3.8 mainline that fixes several issues including, a fix for issue that prevents booting OS with SD card inserted, a fix that cleanup orphan reservation if truncate fails.
