Could you tell us something about the system's hardware, your FreeBSD version, and in particular, the output of `sysctl -a | grep timecounter` run as root? IIRC, some (older) processors had troubles similar to what you seem to be describing, when used with certain values of "kern.timecounter.hardware". You might experiment with setting "kern.timecounter.hardware" equal to each of the other values given in "kern.timecounter.choice" and seeing if the problem rectifies itself (or, possibly, becomes worse). YMMV, of course ;-) HTH, Kevin Kinsey
