SubjectStrange system-clcok behaviour
I am having some very strange behaviour from my system clock.  I am not sure 
that it is really a kernel problem, but I don't know where else to look. The
problem is that my kernel does not keep consistent time. It doesn't have a
regular drift, but instead jumps radically every once in a while. I have had
this problem since switching to the 2.4.xx kernels (never with the 2.2.xx
kernels),and am currently running 2.4.9. This is a PentiumII laptop, and the
kernel is compiled with no APM support. Please don't recomend ntpd, I've tried
it, and it doesn't work well for this problem. If there is any other
info I can provide (or if someone can point me in another direction), please
let me know.

adjtimex -p reports:
mode: 0
offset: 0
frequency: 5065932
maxerror: 16384000
esterror: 16384000
status: 65
time_constant: 2
precision: 1
tolerance: 33554432
tick: 10000
raw time: 1002095853s 812935us = 1002095853.812935
return value = 5

Here are some snippets from running adjtimex -c:
the clock was synchronized against the hardware clock just before the trace
I have validated that the hw clock keeps at least reasonably accurate time.
