I don't think this is a specific kernel problem because I have the same thing
happening with an FC1 (2.4 kernel) machine. Identical problem, ntpd is
running, but clock does not get adjusted until I either reboot or restart ntpd.

I've seen this over the last couple of days, missed the end of several films because of it :-(. It appears to be a problem with the 2.6.10 kernel since downgrading to 2.6.9 solved the problem.

There have been a couple of threads on linux-kernel but nothing
conclusive so far as I can tell
http://marc.theaimsgroup.com/?l=linux-kernel&m=110414701624856&w=2
http://marc.theaimsgroup.com/?l=linux-kernel&m=110217676010185&w=2
and possibly
http://marc.theaimsgroup.com/?l=linux-kernel&m=110306288417182&w=2
(although I don't use USB so I'm not sure)

Someone suggested using tickadj to change the kernels tick time, so I
installed adjtimex and ran adjtimexconfig which figures out the correct
adjustment and sets everything up to be configured on boot (at least on
Debian) and the clock is now holding the time OK even on 2.6.10. You
could also probably just fiddle by hand using tickadj until the time
seems ok. I guess it'll need to be redone/removed when the kernel is
fixed.

Ian.
