For FC5 and onward, for x86-64, there is no -smp kernel.
There are a number of reasons for this

- Cuts down on an extra set of images for the ISOs.
- Increases code-coverage, Everyone runs the same code.
- Is only a tiny performance hit, and work is underway
to make this completely go away.
- Over time, it'll become more difficult to buy a UP x86-64,
when dual-core & hyperthreading become more widespread.


Thanks for the info.


If drivers don't work in SMP, they need to be fixed to do so.


I'll pass along the message to the rt2x00 developers.
