I have failed to get it working. I tried both of the options under CPU features to enable the APIC, with both settings of the kernel flag. I also tried a SMP kernel, with no flag. None of these showed any NMI interrupts in /proc/interrupts or any different behaviour on unplugging with the network active. Is a serial kernel likely to do anything in this case?
