What I have gathered from your configuration example, it appears the FWSM is set up behind the MSFC. Since the outside interface on the FWSM is configured with an IP address of 10.2.2.2/24 then the SVI on the MSFC for the same vlan needs to have a different host address, such as 10.2.2.1/24 for example. There is no way for traffic to reach the MSFC from the FWSM if they both have the same host address. Are you running OSPF between the MSFC and the FWSM or are you using static routes?
