Why not just . Didn't get that. Till now I was trying to get away with standard distro's ressources since I have to give some of the work in others hands which I do not want to confront with kernel-compiling stuff. > Looking at your BUG, did you look in the .config to see if you > had MAXSMP or NR_CPUS defined?
