    Strange problem.

    On an IBM xSeries 335 machine with TWO P4 HTT cpus (mptable, dmesg output
    enclosed) FreeBSD -CURRENT will sometimes detect both the physical CPUs
    and will sometimes detect only one.

    FreeBSD 5.3 reliably detects the 2 physical / 4 logical CPUs that are present.

    Any suggestions on how to debug this?
