Furthermore, which kind of changes of the directory are you referring
to? Reading `dired-buffer-stale-p', the dired buffer shall be reverted
only if there is a new file in the directory, or a file is removed. Just
changing (the timestamp of) a file in the directory shall not revert the
dired buffer.

A second thought: auto-reverting dired buffers has been changed to use
file notifications. Does it make a difference, when you eval the form
(setq auto-revert-use-notify nil) ?

Best regards, Michael.
