Apparently there is some type of conflict introduced in 2.4.13's APM code. I finally got 2.4.17 to boot with SMP enabled after I disabled APM. Though APM is not SMP safe, I have been using successfully it for its power-off feature.
I will look closer at the 2.4.13 APM changes to try and determine what broke my SMP.
