Dapper Guide Multi-core instructions

How to enable Multicore Support
This should work for both Multicore systems and SMP systems
sudo apt-get install linux-686-smp

While the instructions are technically sound, they do not necessarily work.
You want to include linkls to the current discussions and wiki page looking at resolving the problems. Mainly with Intel Core 2 Duo and recent motherboards.

From personal experience - it doesn't just work.

Main wiki page:

I have installed the smp kernel you listed, and it has worked flawlessly so far. System is a Dell E1705 laptop with all-Intel hardware and 2ghz Core 2 Duo. Both processors are recognized and there has been no instability thus far.

EDIT: Just for reference, I installed the SMP kernel about two weeks ago.

I concur. It's not that simple. After installing, you have to go and edit /boot/grub/menu.lst , and modify it so that you boot to the "generic" kernel. The linux-686-smp package depends on the linux-generic package, since the linux-generic is actually a 686-smp kernel.

Hope that helps (at this late date :???: ).

Does this need to be done for Edgy also?
