Trying to find a realtime patched kernel for Etch

I realise there are no realtime patched kernels on the main debian repo's, and
have been googling a bit, and found this.

http://pkg-freebob.alioth.debian.org/lowlat.html

It says to add the line below to /etc/apt/sources.list, but after running
apt-get update, and opening synaptic, I can't find a source pkg for the
2.6.21 kernel.

deb http://pkg-freebob.alioth.debian.org/debian unstable main

The only 2.6.21 kernel there appears to be a realtime patched one, but is a k7
one. As my machine uses a 1.3GHz celeron, I don't suppose this is going to
work, is it?
linux-image-2.6.21-2-k7rt8

Anyone any suggestions to get realtime working, if the above kernel is a no
goer?

The problem I have is that when starting jackd there are loads of xruns
showing in it's messages, and when playing a music app, horgand for example,
I am getting static like noise every so often when playing notes.

Any help/suggestions appreciated.

Nigel.

Ideally I was looking to resolve the problem on my Etch, and Lenny installs.
Someone I know on the LAU list has just mentioned 64studio. Annoyingly the
full install is only available on dvd for i386, and I can't burn dvd's. I'll
have to try the live cd version.

It would be nice to fix realtime on Etch, and Lenny though, and it looks like
I'll have to get my hands dirty, and attempt to compile a kernel using the
realtime patches.

Is that in the archives?

Add this to /etc/apt/sources.list:
deb ftp://musix.ourproject.org/pub/musix/deb/ ./

After apt-get update, you will see various 2.6.21 rt patched kernels, modules
and sources (as well as most recent Ardour and Rosegarden to use them.

This repository is slow mollasis, however.

Thanks for that David. Slow is no problemo, as I'm on dialup.

With the help that's been offered, I'll get realtime working on Etch, and
Lenny, one way or the other.
