[ Re-sending... Please feel free to comment, even if you don't have "The Solution". I'd just like to get some feedback. ] Hello everyone, I'm using 2.6.20.7-rt8 on a P3. I've noticed that the frequency offset of my system clock (computed either by ntpd, or by hand) changes drastically across reboots. By drastically, I mean +/- 60 ppm every time I reboot. Apparently this is caused by some imprecision in the frequency estimation done in calculate_cpu_khz() (arch/i386/kernel/tsc.c) My brutally crude work-around was to skip the computation altogether and hard-code the "correct" value for cpu_khz. http://linux.kernel.free.fr/cpu_khz.adlink Has this issue been investigated more thoroughly by other users?
