I read at

that you should use the Realtime Preemption Patch and then enable it.
I'm running a 2.6.12 kernel patched with this and using also the realtime-lsm 
module.
But now I'm confused, because
1) "less /sys/block/hda/queue/scheduler" gives me "noop [anticipatory] 
deadline cfq", so where is the realtime preemption? Is it useful since you do 
not even mention it? 
2)I discovered that the rlimits way it's better: is it true? Is it also 
simpler than loading the realtime module, which I can do in a straightforward 
way?

Byez!
