When I right click an external hard drive (in my case Western Digital, 750GB) and chose "Safely remove", it always gets me out of session and the computer hangs in that screen showing that "panic occurred switching back to text". CapsLock led flashes and the computer is frozen, I must force a shut down. It is an old bug, I saw it also in Natty.
When I only unmount a hard drive, it works, but that is not the same with "safely remove".
