| |
Hi,
with default boot I got tsc clocksource selected on an debian's 2.6.18-3-k7 SMP build (but UP machine). ntp keeps bothering me with this message: frequency error 512 PPM exceeds tolerance 500 PPM
If I remove ntp's drift file and restart, it goes fine for a while and then it goes with that behaviour again. If I remove ntp's drift file, then do a: echo acpi_pm >/sys/devices/system/clocksource/clocksource0/available_clocksource ; and then restart ntp, it goes fine "forever".
Any toughs, something I should look at?
I'll be glad to give more feedback.
I don't know if that happened with 2.6.17, but I'm pretty sure that with 2.6.16 it was fine.
