Hi, I've downloaded the 2.2.18 prepatched Kernel and rtlinux 2.3, because the 2.2.18 is much smaler :-). The Kernel compiles without any mistakes, and seems to run ok. I can also compile the rt code, but when I try to load the rtlinux modules, he prints a lot of errors about unresoveld symbols. Can somebody help me?? Malte
