SMP in linux is rock solid..what is causing issues is hyper threading which fakes a second cpu to try to keep it's excessivly long pipeline full. Get two p-3's or two athlon's or run the two p-4's without hyper threading and smp will work just fine. Hyperthreading is a godod idea that unfortunatly has to be used to patch an inefficient cpu design.
For those who don't know, simply adding the keyword "noht" at the end of the "kernel" line on grub.conf will turn it off when you reboot. So you would end up with a kernel line like so:
kernel /vmlinuz-2.4.20-31.9.progeny.6smp ro root=LABEL=/ noht
(No, this is not a CentOS box ;)
I've been doing that on all HT-enabled boxes I have. HT is of doubtful use for server applications. If your server runs Windoze and you like using M$ Office apps on it, well, maybe you have some gain...
