No, it should not happen when disabled, you should see messages saying "Invalid use of FPU in Xenomai context at xxxxxx" on the kernel console. That is probably another bug. Is it possible for you to run your example without Xenomai at all ? Just to be sure that we do not hit a Linux bug. -- Gilles.
