Neither I see a new password request, nor I see a connection as user
"Christoph". And it did some initialization actions, until it hung.

Unfortunately, you haven't shown the whole trace, which makes it hard to
follow the complete flow inside Tramp.

Could you, please, rerun a clean test:

- Stop Emacs
- Remove file ~/.emacs.d/tramp (which keeps cached values)
- Start "emacs -Q"
- Make your settings, like (setq tramp-verbose 6)
- Rerun your test
- Show the complete debug buffer

If the debug buffer contains sensitive information, you could send it
off-list. It doesn't contain passwords, 'tho.
