Hi there, I am having issues with clock drift on my G4 Mac mini. The clock drifts so much that even ntpd can't keep up with it. I keep getting messages like "time reset +2.404131 s" from ntpd approximately every 15 to 20 minutes.
Also, the drift ntpd records in /var/lib/ntp/ntp.drift keeps growing until I get messages stating "frequency error 507 PPM exceeds tolerance 500 PPM", and the like. The only way I know of "fixing" these is to stop ntpd, remove the ntp.drift file and start ntpd again. Then the frequency error slowly starts to rise again, until it once more exceeds the maximum of 500 PPM. The time it takes to get to this point varies, but this usually occurs once a week or once every two weeks. I have experienced this problem with every 2.6 kernel I have run on my Mac mini, up to and including the current version 2.6.18-4-powerpc. I have never experienced such problems running OS X on the same machine (although I haven't run OS X that much), so maybe this is a kernel bug? Any help pinpointing and/or solving this problem is appreciated. My /proc/cpuinfo is attached; I think it would also be useful to know if people with the same machine have similar problems or not. Cheers, Bram Senders
