SNMPv3 issues after Firepower Upgrade on ASA SFR module and 7050 IPS

[Solutionary]

We upgraded our sensors last night   SFR   6.5.0.4  and the 7050 to 6.4.0.9.   After the upgrade completed, we lost SNMP from our Science Logic device.

I tried SNMPWALK   but I get :

snmpwalk: Unsupported security level

I also created a new SNMPv3 user called test    and can see the account in snmpd.conf   but SNMPWALK shows:

snmpwalk: Unknown user name

Has anyone else experienced this issue?

I do have a TAC case opened.
