    #sysctl kern.timecounter.choice
    kern.timecounter.choice: TSC(800) ACPI-fast(1000) i8254(0) dummy(-1000000)

    Last box I had trouble like this on was K6-2/500 on Asus p5a mobo.
    Setting to i8254 worked in that case. If you've not tried all the
    possibilities, do so now.

    I must also say that I *think* I had a box (around PII 200) that I
    never got this resolved on (but I'm not sure how hard I tried....)

    HTH,
