    anyways, i still see the mysterious pauses which do not show up in the
    preempt_max_thresh.

    ah, and btw: what does the /proc/sys/kernel/kernel_preemption tunable do
    with PREEMPT_REALTIME enabled?

    mango:~# cat /proc/sys/kernel/kernel_preemption
    1

    [all the other VP tunables are not available anymore]

    mango:~# cat /proc/sys/kernel/voluntary_preemption
    cat: /proc/sys/kernel/voluntary_preemption: No such file or directory
    mango:~# cat /proc/sys/kernel/hardirq_preemption
    cat: /proc/sys/kernel/hardirq_preemption: No such file or directory
    mango:~# cat /proc/sys/kernel/softirq_preemption
    cat: /proc/sys/kernel/softirq_preemption: No such file or directory
