You can do that via loader.conf or sysctl.conf. The first option should be more reliable. What you see can mean two things (at least that's what I can think of): - problems/quirks with HPET hardware on your system - problems with IPI forwarding of time ticks between CPUs Maybe there would be additional requests for debugging info if you are interested in pursuing this further and are able to provide the info. > I'll do a reboot now, to see if there will be a kernel panic at reboot, I > compiled the kernel now with all the debug options.
