One of the first things I would check is top, see if it
see's two cpu's. I would also check dmesg see if it lists
two cpu's, I do not know how it lists a logical cpu, but I
am sure google can find it out for you.
I know many moons ago when I tried the installer on sarge it
only seen one cpu, seems that they do not include an smp
aware kernel with the installer, that might of changed a
while ago. If that is the case just make your own, or
download a smp aware kernel with apt-get. That was with dual
amd MP cpus, was many moons ago, probably going on a good
nine months.
You just might want to keep it to one cpu as HyperThreading
has a security bulletin against it, found in the BSD's
probably effects all OS's. Check the news its all over the
web if you want to find out more.
