I've checked the *tramp ...* buffer and I found it empty.

... so I've tried this, the *tramp ...* buffer was still empty, but the
*debug tramp ...* was not. I'm attaching its content, gzipped since it
is 160 Kb (yes, I've cleaned it up just before doing the test, but still
... :-).

AFAICT, in that log I see the password being delivered to su (I did the
test with the "/su::" prefix), luckily not reported in the log, and I
also see the prompt of a root shell clearly returned to tramp, so I
don't think the issue is the "waiting for a password". Rather, it looks
like that in the vc <-> tramp dialog someone fails to recognize that the
login has been properly done.

Thanks for your feedback,
Cheers.
