I've followed the SMP lists for some time and honestly I've lost track on whether it's a good thing to enable SMP in my kernel or not and whether there are special options for HT in the kernel config. Sorry this is so vague, I'm not having a problem as I'm running my custom kernel with HT/SMP disabled for now. In my searches the consensus seems to be that if you don't have 2 real cores don't bother with SMP and I want to confirm that is still the case. Any info anyone can offer would be greatly appreciated! Thanks!
