You probably have some poroblems in your kernel port - check the RTC
driver and related modules like I2C etc. Of course this depends on
the NTP configuration you use, but the only kernel interaction I can
think of that could cause this is if you interact with the RTC. [I
guess that normal network traffic is working fine on your board.]
BTW: ELDK 4.1 comes with a 2.6.19.2 kernel - is there a special
reason that you use such an obsoletel kernel tree?
Best regards,
