Welcome to PLUG. I have some PCs that act a bit random in my house,
too ;-)

FWIW, I use fedora (mostly) and suse (some) and notice with fedora that
that both eth0 & eth1 are brought 'active' or 'inactive' acting as if
one device when I use a gui to do it.  Can't speak for doing it from the
CLI, snce I haven't bothered.  I think suse has the same behaviour, but
can't verify ATM.  That's a bit peripheral to your post, but maybe
indicative of how the interfaces are handled if you also do it from a
gui?  Dunno, sorry not more useful ;-)
