There is already a check for this in the cpufreq code, but maybe it doesn't work when TSC is selected at boot? sysctl kern.timecounter.hardware="i8254" or sysctl kern.timecounter.hardware="acpi-fast" http://lists.freebsd.org/pipermail/freebsd-current/2003-August/008718.html If it works, put it in /etc/sysctl.conf -- Nate
