Hmm, I've tested this on a P54C-100MHz, Celeron 300A, P2-400MHz, K7-650MHz, K7-750MHz and K7-800MHz, all produce the correct results, all have machdep.tsc_freq .. All the machines range from FreeBSD 4.0-RELEASE to 4.2-STABLE Perhaps if you specify in your kernel to use CLK_USE_TSC_CALIBRATION Thanks for the tweaked version :) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
