Update Ubuntu 11.10 to Kernel 3.2

So you want to take advantage of the new features the new version of Kernel 3.2 has to offer? Fear not, simply copy and paste the below commands and you’ll be good to go!

Some of the main features along with many others of 3.2 are:

  • Ext4 now supports block sizes up to 1MB, which decreases the time spent doing block allocations.
  • Btrfs delivers detailed curruption error messages, so instead of something like ‘block xyz is bad’ you get this:
    btrfs: checksum error at logical 5085110272 on dev /dev/sde, sector 2474832, root 5, inode 32583, offset 0, length 4096, links 1 (path: default/kernel-0/Makefile)
  • Lots of filesystem performance improvements.
  • A process scheduler divides the available CPU bandwidth between all processes that need to run.
  • Inclusion of a TCP “Proportional Rate Reduction” algorithm, developed by Google, which improves latency and the time to recover.
  • Support for transmission of IPv6 packets as well as the formation of IPv6 link-local addresses and statelessly autoconfigured addresses on top of IEEE 802.15.4 networks.
