    yeah, i suspected something like that - the PREEMPT_RT latency numbers
    were so out of whack with anything i've measured on similar boxes. The
    debugging features on PREEMPT_RT are powerful but have a high overhead.

    could you send me your PREEMPT_RT .config? (whichever version you have
    handy) That's the easiest way i can tell you which options to watch out
