We have installed 15 EPIA systems and in a few months have had 3 mother 
boards replaced for problems with the on board vr interface.

A bit of a search reveals a large number of reported problems from most
version of BSD, Linux and even the odd MS user. Some have added a PCI NIC.
Others swear they have no problems and that their systems are solid.

There seems to be some hint that interference from the power supply gets into
and upsets the interface a few months down the track when the ESR of the
power supply capacitors increases.
