Hi All, I need a 2.6.32 kernel for my soundcard to run, but I can't find it by: apt-cache search linux-headers only 2.6.28 is available on my ubuntustudio 8.04 machine and 2.6.31 on my 64studio 3.0 machine. How can I get a 2.6.32-rt kernel? Do I have to compile it myself? Thanks, Martin

By Downloading the 2.6.32 kernel source and then downloading a patch (which does not exist yet) to make it rt.

This is the important question.

You should NOT do this on Ubuntu Studio (or any Ubuntu) unless you want to fix real borkage. Try upgrading to the latest Ubuntu Studio, it may have 2.6.31 at least (not sure on whether they have 2.6.32, maybe in the latest alpha?). A bit of an explanation, in Ubuntu (like most distros) the kernel version and various packages in the system are closely tied together, such that a jump from 2.6.28 to 2.6.32 is likely to result in quite a few problems.

It is reported that my soundcard (Native Instruments Audio 4 DJ) works best with 2.6.32 and that kernel 2.6.30 is required as minimum. The card uses the snd-usb-caiaq module and 2.6.32 is higly recommended because of Git commits a9b487f<http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git…7f>, ac9dd9d<http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git…9d>. I don't understand these in detail so I don't know how they would affect performance.

I installed a 2.6.31 kernel via apt-get on my 64studio machine but booting the kernel doesn't work ("this kernel requires the following features not present on your cpu: pae"). If anybody can help with this - thanks a lot! A bit of an explanation, in Ubuntu (like most distros) the kernel

version and various packages in the system are closely tied together, such that a jump from 2.6.28 to 2.6.32 is likely to result in quite a few problems.

I understood that now, though I hope I will not have to wait for the next release to get my card to work... Thanks again, Martin

You probably just need to install the kernela headers and compile a new version of alsa from source. Patrick Shirkey Boost Hardware Ltd

Basically the kernel was compiled with PAE support and your cpu doesn't support it, I believe. Didn't even know that was an issue, but you should contact 64studio and ask about this, they probably have a separate kernel without PAE compiled in.
