I have an AMD Athlon64 X2 machine running SuSE 10 (x86_64) on an Nvidia Nforce4 Ultra motherboard, and have noticed that the system clock has become unstable (it runs too fast). Not sure when it occurred, but I have been getting a lot of error messages
I've had that same problem with sl9.3 and amd64-x2. I've found that the problem comes from the irqbalance programm. It is compiled with class_policy[IRQ_TIMER] = POLICY_ROTATE; witch will divide the timer Interrupts between both cores. I've change the source to class_policy[IRQ_TIMER] = POLICY_IGNORE; and since recompiling and reinstall of irqbalance my clock is working perfect. NTP has no more problems to hold the clock stable. I dont know if irqbalance is the main problem but for me now it is working. :-) And it is working with all different type of timer (pmtimer, tsc ...) no more commandline parameters needed. With original kernel and KOTD's. Gruß Carsten P.S. Wer Fehler in Rechtschreibung oder Grammatik findet darf sie behalten. Englisch ist leider nicht meine Stärke.
