Nexus 7K F2 and Netflow

Is anybody successfully collecting Netflow from a N7K running F2 line cards with Sup1?  I'm on 6.2(6), I've applied the TCAM hardware ACL (which is still required in 6.2(6)) and no love.  In packet captures on the collector I see the CFLOW packets hitting the server, but the flowset fields in the capture contain the field descriptions (I think) rather than the actual data they are supposed to contain.  See the attached screenshot.  We are sending the export to SolarWinds NTA.

flow timeout 0

flow timeout active 60

Applied as:

ip flow mon nta-mon input sam nta-exp to layer 3 interfaces (VLANs).

I've had both TAC and SolarWinds engineers looking into this, I suspect this is a Nexus issue more than SolarWinds though (if not a configuration problem).  I've already tried using the netflow-orginal template and switching to v5.

I found another customer with this same issue running 6.2.6 code and nothing worked until we upgraded to 6.2.8a - then all worked as expected.
