Just for the record, here are the default values for the kernel variable "CONFIG_NR_CPUS=" for the following arches: x86_64=1 x86_64.smp=8 i686=1 i686.smp=32 ppc=4 ppc64=64 s390=32 s390x=64 ia64=64 These values are the default values for RH ... the only one I see as a major problem actually is x86_64 ... I would think that 8 might be too small with the dual core machines out there. I would think 4 dual core machines would show up as 8 CPUS ... anything more would probabl ynot be recognized correctly. Currently we are not changing these values in either the main or centosplus kernels, but we might set all the smp supported config files to 64 in the centosplus kernel for future versions.
