Hi Jason, and sorry to pop in, but now you got me guessing if I should follow your lead too ... This is what I get in here: [gonz...@inferna ~]% grep Time /var/run/dmesg.boot Timecounter "i8254" frequency 1193182 Hz quality 0 Timecounter "ACPI-safe" frequency 3579545 Hz quality 850 acpi_hpet0: <High Precision Event Timer> iomem 0xfed00000-0xfed003ff on acpi0 Timecounter "HPET" frequency 14318180 Hz quality 900 Timecounters tick every 1.000 msec Should I change kern.timecounter.hardware to i8254 too??
