Hmm, interesting. I would guess that this means that you shouldn't run floating point code in the kernel. Think about it for a moment; to whom would you deliver a floating-point exception? It probably fails because the FPU initialisation is lazy, and if you haven't initialised it before you use it, you'll die screaming. mike
