Nexus 7009 NX-OS upgrade issue




I have just upgraded a Cisco Nexus 7009 from 6.2(2) to 6.2(8a), but are having some trouble.

The M2 module (N7K-M224XP-23L) appear to stop forwarding data of certain types after av while. The card is in production so I have not been able to troubleshoot much, but the symptom is that after 3-4 hours of activity.

For instance, at a certain point, no dhcp request found its way to the DHCP server. And the only ones affected was connected to the M2 linecard. Physically resetting the port, and everthing works fine for a few hours. Moving the link to an E2 card, ant it is stable. Moving back, same thing happens again after a few hours.

So does the M2 card have issues with trunk ports? 
The last test I did was with a standard trunk config:

interface Ethernet4/5
  switchport mode trunk
  no shutdown
