OK, so I've pushed the patch to the master branch. It will also be
merged into the emacs-27 branch after the release of 27.1.

Strange. The patch doesn't touch anything which is relevant for
tramp-test29-start-file-process, AFAICT. OK, same procedure as very
year: apply the appended patch to tramp-tests.el, and rerun the
test. The debug buffer shall tell us more.

Best regards, Michael.
