I've tried grabbing this patch and it does pretty bad things on my testing VM, it just gets stuck 
early in the boot process and doesn't show any progress. The VM never even gets close to starting up 
all the cpus (usually dies around the lockdep self-testing).

Are there any other dependencies?


Thanks,
Sasha
