[K12OSN] Network unreachable.

[James P. Kinney III]

This is beginning to sound like a module loading issue. Because you are
swapping out cards presumably with different drivers and certainly with
different MAC addresses, each change will require updating the
configuration of the devices.  I am unclear on what distro you are
running. 

Second note. Modules get loaded in the order they are found in a file
called /etc/modules.conf (for current systems. Older systems
used /etc/conf.modules). However many motherboards try to power on
devices based on bus ID. That is typically done low number to high based
on slot location physically relative to the CPU location. So the top pci
slot is 0, the next one down is 1. But some boards do this in reverse
(high to low). So the removal of the second nic causes the first nic to
function properly which suggests the configuration of the second is out
of order, has the wrong MAC on both, or all of the above. The mii-tool
mentioned earlier will give you data on the interface specifics as well
as providing a means to adjust hardware settings (like full-duplex,
etc).
