Or is it enabled by default? Yes, you need to enable CONFIG_PREEMPT. If it is not set, kernel preemption is disabled. If it is set, you have a preemptive kernel. It is set by default in the standard defconfig (on i386, at least) but you may need to enable it if you use an old config. Robert Love -- Kernelnewbies: Help each other learn about the Linux kernel.
