Are you sure?
If desktop-mode is enabled and you have a buffer like /etc opened as
sudo in your saved buffer in desktop, at each time you restart emacs,
desktop will open this buffer and you will be prompted for sudo
password.
So you have to kill these buffers before quitting emacs.
You can try to set `desktop-files-not-to-save', but it never worked for
me. :-(
So i use this:(add to .emacs)

,----
| (defun tv-list-tramp-buffer-file-name ()
|   (let ((desktop-info-list (mapcar #'desktop-buffer-info (buffer-list))))
|     (loop for i in desktop-info-list
|        if (and (listp i)
|                (stringp (car (nth 8 i)))
|                (string-match "^/su:.*\\|^/sudo:.*\\|^/ssh:.*" (car (nth 8 i))))
|        collect (nth 2 i))))
| 
| (add-hook 'desktop-save-hook #'(lambda ()
|                                  (let ((del-buf-list (tv-list-tramp-buffer-file-name)))
|                                    (dolist (i del-buf-list) (kill-buffer i)))))
