As others stated, it's probably an app or configuration issue related to the upgrade.
ICS is a big change from HC, and there are thousands of changes to the code base. I know it's a hassle, but a factory reset will wipe away the apps and data cache that may be causing this problem. You can use Google Backup to save most of your stuff, and any paid apps will be saved on Google Play. Just remember that backup and restore uses a DATA connection, so if you have a 3G/4G model and don't have a large or unlimited plan, then make sure you use WiFi to backup and restore.
