Do you have HAL daemon running?

I recently had the same problem, and it turned out that momentaneously
shutting down the daemon allowed me to unmount filesystems. See
/usr/local/etc/rc.d/hald.

Hope this helps.

Note: the HAL daemon is used by desktop environments like Gnome or
Xfce, so if you use on of them, it is likely you have HAL daemon
running.
