Proxy ARP failure on ASA 8.4

Any of you guys seen issues with Proxy ARP for NAT addresses in 8.4 code on a Cicso ASA? Had a horrible issue with trying to get a new firewall to pass traffic. It would only respond on the physical IP address and none of the NAT addresses - after validating security and routing, the only remaining problem was a failure of the ASA to proxy ARP for NAT.

    Proxy ARP replies to the upstream router aren't being sent

    We figured it out...proxy ARP is broken when you use an etherchannel for that code. Single links work with no issue...TAC is working on it.
