Comment 11 for bug 290498

@Alessio: not quite.

I've installed the 2.6.28-2-rt kernel on my desktop and my laptop, which have nothing in common hardware-wise. The kernel does see the second core, but (reportedly) it's unusable. Running 'top' and pressing '1' I get:

Cpu0 : 0.7%us, 0.3%sy, 0.0%ni, 99.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
Cpu1 : 4.3%us, 0.7%sy, 0.0%ni, 0.0%id, 0.0%wa, 95.0%hi, 0.0%si, 0.0%st

The second core remains at 95-99% no matter what.

Plus, if I try to reboot, by using the user-switch applet on my desktop or by pressing the power button on my laptop for the dialogue to show up, the computer stops responding to keyboard and mouse events (I do see my temperature and CPU monitor applets updating themselves, so the computer does not hang entirely), and the computer does not reboot.

Let me know how I can help debug this.
