Firepower: Mgmt interface failing after upgrade to 6.6

Hi,

 

I'm facing a weird situation. Right after upgrading a FP1210 from 6.4 to 6.6 the management interface stopped responding. I lost connectivity to the FMC. If I connect the interface directly to my laptop it works, however when I connect it back to the same switch it was before the upgrade, it doesn't negotiate the link and remains down. The switchport works fine as a connected other devices without issues.

If I reboot the firewall, the link is up for a few minutes while the device is booting, but once fully boots, stops working.

 

Any clue?

 

Regards.
