Re: SMP Documentation

Thanks for your comments and inputs. I am reading the FreeBSD docs. and
planning to acquire a freebsd kernal design book. And I need a dev system
to be setup before I jump in start experimenting. As of know I am going
through the changes being made.
Happened to go through

http://bsd.slashdot.org/story/03/10/03/0158217/irc-forum-with-matthew-dillon-of-dragonfly-bsd
Wil be following up in the efnet network as the freenode one is quiet
inactive.
