>Description:
	I just built a new multi-processor kernel, ran two "yes > /dev/null" &
	and the second processor is still idle. This used to work... Here's
	what top says:

CPU0 states: 60.7% user,  0.0% nice, 38.3% system,  1.0% interrupt,  0.0% idle
CPU1 states:  0.0% user,  0.0% nice,  0.0% system,  0.0% interrupt,  0.0% idle

>How-To-Repeat:
	Compile a recent mp kernel.
>Fix:
	Dunno yet...
