I'm testing ubuntu karmic koala and would like to try it with the 2.6.33 kernel. Do I have to compile my own or is there one available somewhere?

You have to compile yourself I think. Ubuntu karmic only comes with 2.6.31 pre-compiled.

But that's also good news, compiling a kernel is quite fun. Its an awesome feeling to boot from something that's your own and there are lots of good guides out there.

Good luck, post back if you need advice.

Please note that the latest stable kernel right now is 2.6.32.2:
http://kernel.org/
The 2.6.33 kernel is currently at RC status.
You can get pre-compiled Ubuntu kernels as .deb packages from here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/
The 2.6.33 RC2 Ubuntu kernel is right at the bottom of that page:
http://kernel.ubuntu.com/~kernel-ppa...e/v2.6.33-rc2/
If you want to compile your own kernel, Debian based distros can use the KernelCheck package that is said to make it easy to roll your own Ubuntu kernel:

I have never tried compiling my own kernel in Ubuntu. I have managed to compile working kernels in Zenwalk and Slackware, since those 2 distros both use "plain vanilla" kernels. If I wanted a newer kernel for Ubuntu I would use one of the PPA kernels in the first link, or I would try using KernelCheck as discussed in the second link.
Here is another article on compiling a kernel in Ubuntu if you want to try it the manual way:

Please let me know if any of those links work well for you.

Thanks, I'll have a go today. I realise that 2.6.33 is still a release candidate. A friend who's new to Linux has installed Ubuntu and has a Leadtek DTV1000s (TV card) which is supposed to be supported in 2.6.33. I have compiled modules from a tarball on my slack box for this card that work but when I tried to compile from the same source on koala I had some fatal errors. I normally don't bother compiling kernels and I'll see if I can get some joy out of downloading from the link you have provided.

I just installed the 2.6.33 kernel and kernel headers at the link provided by tommcd above. No problems and the DTV1000S is working.

Thanks
