<div>You're not the only one. Over time and successive firmware patches we narrowed it down to only 7970's using CNR but behind a specific firewall that had the problem. Since I know you keep firmware versions up to date, check firewall versions and bug lists too. We had so few 7970's that it wasn't worth the risk of upgrading firewall code to fix it, but it may be different for you.
