Subject: NTP on 2.4.2?

Hi,

I'm having problems getting my 2.4.2 kernel to synchronise properly. For
some reason, NTP is insisting on making time offset adjustments.

Is anyone else using NTP with 2.4.2, and if so, are you synchronising
properly?

(I'm using the RH7.0 version of ntp-4.0.99j here)

Works for me. (RH7, ntp-4.0.99j-7, Kernel 2.4.2-ac23 - but worked with
plain 2.4.2, too)

It isn't a GMT vs localtime issue, I presume?

Yes, working fine for me.

Suse 6.3, xntp-4.0.98d-0, mostly vanilla kernel 2.4.2

No, I solved the problem - the 100Hz interrupt wasn't close enough to 100Hz
to allow NTP to do its job.

Are you using fbcon? If so, and if it goes away after starting X, then it is
the "fbcon kills interrupt latency" problem.
