I'm not sure how to fix this though. I don't have a copy of Emacs 24 handy (and I recommend you upgrade to 25), but as a band-aid you should be able to kill the check by setting the `tramp-use-ssh-controlmaster-options' option to nil. That ought to prevent tramp from testing the connection at all (at least, I think it will). In 25 it looks like "host.does.not.exist" has been replaced with a bogus IP address, meaning that you won't time out on a DNS lookup, which is likely what's hanging for you. As for the real root of the problem -- why loading org results in tramp doing this check -- I unfortunately can't tell you! The real "fix", I think, would be upgrading to Emacs 25. Eric
