Configure both sides of the link to autonegotiate for speed and duplex. Issue the shut/no shut command to recover the port. If the problem persists, move the connected device to another port and see if the problem happens there. If neither of these solves the problem, issue the hw-module reset command in order to reboot the switch and reset the line card. You could also upgrade the the Cisco IOS version to the 12.2(25)EWA2 or 12.2(25)SG releases.
Sometimes you have to reset and there should be a window when you can do things like this. If not then policy and how things are setup should be looked at . A router is a computer and things do get hung up occasionally.
