I have installed AEM SP2 on Redhat Linux, I could see as Version 6.0 SP2 after installation. But later I installed following hotfixes in the below link.
Hotfix 6167 *
Hotfix 6446 *
Hot fix 6561 *
Hotfix 6031 *
AEM 6.0 Dynamic Media Feature Pack
cq-6.0.0-featurepack-6431-1.0.0
cq-6.0.0-featurepack-4113-2.0.4
Now suddenly I could see Service Pack details as Version 6.0.0.20150409 which is attached. However all the bundles are either Active or Fragment expect few which I manually resolved and org.apache.jackrabbit.oak-core bundle version is 1.0.13. Please let me know what is wrong. Whether SP2 is installed or not, it is listing in CRX package manager as installed.
