Looks like ""/etc/init.d/networking restart" basically does what I was doing (ifdown/ifup) in one step rather than two. So that works as well. Note that the ifdown command returns the following after the resume:
RTNETLINK answers: No such process
SIOCDELRT: No such process

Let me know what other info I can provide. I'd be happy to help fix this if I can.
