    Hi!

    I'm having a problem, sysctl can't find machdep.hlt_logical_cpus. My machine
    is a dual xeon with hyperthreading enabled, running 4.9. I also would like
    to know what that "Warning: Pentium 4 CPU: PSE disabled" means.

    See below:

    sysctl: unknown oid 'machdep.hlt_logical_cpus'
