I just experimented with this situation myself. I logged into my server (which is keyboard and mouse and monitor less), and logged in as one of my ftp users.
I then typed su, entered in my root password, and then typed in shutdown -r now. The system rebooted itself properly, then when it was backup, I tried -h now and it shutdown fine. This is just a basic install, which has been updated to cooker (12/18). The user is part of the root group (don't ask. I realize this is insecure). but otherwise has nothing special attributed to him. The only thing I can think is are you disconnecting from the telnet session? I close all the windows as soon as I'm done sending the command.
