yup. it means you rebooted the phone in an unexpected way (pull the battery, system crash etc) and therefore the custom kernel settings you have chosen were not loaded, incase you were stupid enough to save as default kernel settings which may cause the phone to crash. you weren't that stupid were you? especially given that all the oc advice warns to make sure your settings are stable before saving as default it would be a really massively stupid thing to go and do now wouldn't it?
