It looks like you have an echoing shell. For better analysis, you shall
set `tramp-verbose' to 10, and show the debug buffer after the test.

In Tramp 2.1.18 (part of Emacs 23.3), there are some improvements wrt
echoing shells. Maybe you try Emacs 23.2, or Tramp 2.1.18 w/o upgrading
your Emacs version.

`tramp-initial-commands' has been removed from Tramp 4 years ago. It was
mainly used for environment settings; these days this is done via
`tramp-remote-process-environment'.
