Better support Ext4 filesystem, an optimized TCP stack and support for thin provisioning in the Device Mapper are some of the most important news just released Linux Kernel 3.2 . The latest version of the kernel also brings with it a number of new drivers and improves, among other things, addressing cones graphics chips from Intel and NVIDIA hardware and wireless of devices Atheros and Broadcom. An update very rich, then, and I would recommend that you install on your Ubuntu.
