UPDATE : December 13, 2010 - 2.6.35 kernel somehow breaks ad-hoc internet sharing from Ubuntu 10.04 to Windows 7 machine.

The default kernel for Ubuntu 10.04 is 2.6.32 while 2.6.35 is Ubuntu 10.10's. If you are like me, who want to stick with the Long Term Support (LTS) version of Ubuntu, but want the 2.6.35 kernel, you can upgrade the kernel relatively safe via synaptic package manager. Still not interested? Maybe this will change your mind, the 2.6.35 brings these updates :

Linux 2.6.35 includes support for transparent spreading of incoming network load across CPUs, Direct-IO support for Btrfs, an new experimental journal mode for XFS, the KDB debugger UI based on top of KGDB, improvements to ‘perf’, H.264  and VC1 video acceleration in Intel G45+ chips, support for the future Intel Cougarpoint graphic chip, power management for AMD Radeon chips, a memory defragmentation mechanism, support for the Tunneling Protocol version 3 (RFC 3931), support for multiple multicast route tables, support for the CAIF protocol used by ST-Ericsson products, support for the ACPI Platform Error Interface, and many new drivers and small improvements. (read more).

 

Want one? Just checkmark pre-released updates (lucid-proposed) in Synaptic Package Manager via Setting > Repository > Updates Tab and then reload, you'll notice kernel 2.6.35 is available for download.

If you have Broadcom 43xx wireless cards, like I do with HP 540 Notebook, you'll need to update these two files :

• bcmwl-kernel-source
• bcmwl-modaliases

To 5.60.48.36+bdcom-0ubuntu5 version, since Ubuntu 10.04 uses 5.60.48.36+bdcom-0ubuntu3 version. You can download them here . Or to save you time, here's the link :

• bcmwl-kernel-source_5.60.48.36+bdcom-0ubuntu5_i386.deb (874.8 KiB)
• bcmwl-modaliases_5.60.48.36+bdcom-0ubuntu5_i386.deb (10.2 KiB)

Happy upgrading.

As usual, apply on your own risk.
