Indeed not the kind of messages one likes to see when upgrading codes, does the route goes into rommon> if it does try recoverying , here is a link for rommon recovery..

Take a look at ios bugs on 12.3 and your platform to rule out issue with code and 3660 , if you try to xmodem another image re-donwload a fresh code from cisco before downloading it to router.
