When booting with verbose enabled (with kern.hz=100), the dmesg shows Calibrating clock(s) ... i8254 clock: 787497 Hz 787497 Hz differs from default of 1193182 Hz by more than 1% Timecounter "i8254" frequency 1193182 Hz quality 0 Calibrating TSC clock ... TSC clock: 3693733736 Hz CPU: Intel(R) Xeon(R) CPU E5345 @ 2.33GHz (3693.73-MHz K8-class CPU) (The full dmesg is available here: http://w.csie.org/~tzhuan/tmp/dmesg-100-v.txt) The i8254 clock is set back to default value after calibrating. Is it reasonable or is there something wrong with IBM x3550? Thank you very much. Tz-Huan
