After emacs boot completed (evil-state is normal).
'C-u C-M-x' function 'foo' then do 'C-x C e' after '(foo)' to enter edebug-mode.
'n' is binded to `evil-search-next'.
'Q' quit and execute (foo) again
this time 'n' is binded to 'edebug-next-mode'

This is something I'm very well aware, I just do not have a solution. The problem is that Evil's decides how to chain keymaps when the state is changed based on the set of other keymaps being active at this point (here edebug-mode-map). However, in some cases it may happen that edebug mode is enabled after Evil changes its state, and then Evil does not chain the keymaps correctly.

In an ideal world there would be some kind of hook to be called whenever the list of active keymaps changes so that Evil can update its chain of keymaps. However, AFAIK there is no such hook so I do not know how to solve the problem.

Can we update the Evil keymap chain by add a hook to edebug-mode-hook?

For now, I tentative change evil state to 'emacs' when edebug-mode on and revert back when it turn off.

Indeed, you could try (add-hook 'edebug-mode-hook 'evil-normalize-keymaps).
