Lennart Poettering of Red Hat, PulseAudio maintainer has blogged in detail about the impact of Real-Time Group scheduling in 2.6.25 kernel. The Real time patches come from -rt patchset maintained by Ingo Molnar of Red Hat which aims to make Linux the first general purpose operating system with hard real time features.

I would recommend giving 64Studio a try. Probably tuned better than Mandrake/iva would be even with this real-time patch.
Sometimes the problem with latency is overly conservative IDE settings ( you may have to get familiar with hdparm to change this) or excessive CD-ROM drive polling.
There are some good docs floating around on this but might be quicker to take 64Studio for a spin.

2 HOURS to recompile the kernel - wow, there's now way it should take that long with recent hardware. I do remember when you could spend that much time at it but that was LONG ago !!!!

I've spent hours today with Mandriva 2008 's 2.6.24-rt kernel, but I could not gain anything from it. Real-time audio is as far from Linux as Tokyo from Jerusalem! I know what I'm talking, since I've even recompiled the kernel (took 2 hours), but I cannot use the great Ardour in Mandriva.I have a good and fast PC. I don't understand why they even are packing applications which shall not work? Ubuntu Studio is closer to the goal. But I'm only dreaming of 10 stereo tracks with latency less than 5ms.
