Run SSHD in the foreground and send debugging output to stdout (sorry don't know the option off the top of my head).

If you can use your mac or something that has openssh client on it. run ssh -vvv and lots of junk will pass by.  It will give more info and maybe a hint as to what's happening.

How long is indefinitely?  Maybe not the case at all but if SSH can't do reverse host lookup stuff you can expect long session startup times.

Debug output from either would help lots.
