And I guess that a lot of people here in d-powerpc know it also because
that's one of the first things that BenH asks people to turn off when
they're having problems with PPC kernels.
In fact, given his advice, I have not enabled "Voluntary Preemption" nor a
"Preemptive Kernel" in recent -mm releases. I just set the standard. Oh,
and I don't keep the 250 HZ that is new with the -mm releases. I go back to
1000 for HZ.
In fact #2, I tried once "Voluntary Preemption" with HZ of 1000 and saw
nothing different for my workload (in comparison with a kernel with any
kind of preemption enabled).
But, perhaps, it is useful for other people.
Hope this helps, Rogério Brito.
