What options do you have in GRUB? I have these two: Fedora Core (2.4.22-1.2135.nptlsmp) Fedora Core-up (2.4.22-1.2135.nptl) The former is the SMP kernel (smp at the end), and the latter is the uni-processor kernel (hence the -up). Do you have both of these, or do you have only thee 2.4.22-1.21??.nptl kernel? -- Well after install, grub only had the 1 entry for the non-smp kernel, and I wasn't sure if it had installed both, so I was gonna bring it up in single-proc mode and make sure the rpms and everything was there first.
