[LAU] an rt kernel for ubuntu 8.10 ?

Greetings, As some of you know, I've had nothing but trouble with Ubuntu's rt kernel, specifically 2.6.27-3-rt from the current repos. As a result I've been working in non-realtime, and I'm not happy about it. So, what's my best procedure here ? Shall I compile my own kernel, and if so, what's the currently recommended kernel source package ? I want decent realtime performance from this machine, a 2 GHz notebook, and I'm willing to do some building if necessary. Is the patch for ALSA (that showed up on this list) included in any contemporary sources ? Is anyone here running Ubuntu 8.10 with an rt kernel, and if so, which one ? Best, dp
