I have a custom kernel (i386) that I want to run on a machine that might have 2 cpus, but I want to only use 1 cpu because I'm not 100% sure the locking is right in the new code. I went to turn off options MULTIPROCESSOR, but it seems that is now non-optional. Is there a compile-time way to disable cpus beyond cpu0? Or should I use cpuctl? or ? Thanks, Greg
