I have a second switch (2924XL) in a remote site and one port is behaving the same. I reboot the switch and did "sh post" the result is "POST FAILED: FastEthernet0/19" I've check the cisco web site and found that this is hardware failure. I execute the same command in the original problem switch without rebooting it because its on production, and have the following results;
FastEthernet0/9 failed front-end loopback test
FastEthernet0/10 failed front-end loopback test
FastEthernet0/11 failed front-end loopback test
FastEthernet0/12 failed front-end loopback test
FastEthernet0/20 failed front-end loopback test
I guess I need to send it for RMA. Forgot to say that I did check the log and there is nothing there but "up/down interface".
