We are neither able to start or reprovision the user profile application after installing the SP-1 on the sharepoint 2010 enterprise environment. Is it a known issue?
I think it is a known side effect when installing June CU.
You can either uninstall .Net 4.0 or force FIM to use .Net Framework v2.0

http://sharepointinterface.com/2011/07/05/crashing-owstimer-exe-after-sharepoint-2010-sp1-installation/ I had this problem as well when I installed the service pack in my virtual environment. Although I was able to completely blow it away, I still get encryption errors now after installing the service pack and correcting the errors in this article. It is all related to the Forefront Identity Management services.
