Since you already have debian sarge installed you might consider adding packages from Demudi/Agnula: http://demudi.org/ At the very least you should be able to use their kernel .debs. I'm not sure because I haven't used demudi yet myself, but it may be as simple as adding a demudi line to your /etc/apt/sources.list and apt-get install'ing the appropriate package(s). For what it's worth, I do audio work on a debian sarge box. I'm using a patched 2.6.x kernel. Others are having good success with low-latency patched 2.4.x kernels on debian as well. I doubt differences in processor optimizations between debian and mandrake are your problem. Especially since you say you have the same kernel .config for both installations. -Eric Rz.
