You were a great help! What I learned is that board has gone through a lot of 
changes (chipset, etc.) between Version 1.0 - 4.1 (I have Ver. 4.1). What is 
needed to fix the issues differs depending on the chipset. Mine works fine with 
the native r8169 driver as long as IOMMU is enable in the bios. I'll try 
disabling in the kernel to kill the Page_Faults on boot.
