[Voyage-linux] Clock Drift

[Jordi Puigsegur]

I run into the same problems a couple of weeks ago. First I tried disabling
mfgpt and it solved the problem but left the watchdog driver not funcional.
Later on I undid this change, activated again mfgpt and installed adjtimex
and ntp. My system is now working in perfect sync.

I've described this configuration in a wiki (
http://code.google.com/p/wfrog/wiki/InstallOn_Alix3D2_voyageLinux0_6_2#Clock_sync).
wfrog is the open source weather logger I'm running on the Alix 3D2.

Hope it helps!

Jordi.
