Looking at the WCHAN, I'd speculate that it's waiting for DCD to become active. Are you using a proper cable with handshaking, or a three-wire cable? See what stty thinks the port is set to. It probably has clocal set, but shouldn't. See if you can unwedge it by setting -clocal with stty, then pick a proper cable or gettytab entry.
