I've found that running git annex add on a directory in a direct repository freezes. Example output:

    > git annex add Signs\ \(2002\ Film\) --debug

    ok

Lots of files, ending in:

    add Signs (2002 Film)/VIDEO_TS/VTS_13_1.VOB [2015-02-22 10:56:49 GMT] chat: git ["--git-dir=/Volumes/plato/Films/.git","--work-tree=/Volumes/plato/Films","-c","core.bare=false","hash-object","-t","blob","-w","--stdin","--no-filters"]

It then hung for just under two hours before I hit ctrl+C. The files are on a remote SMB server mounted via OS X (hence direct mode) and git annex is being run on an OS X machine. git version 2.3.0, git-annex version 5.20150205. Both installed using homebrew. Any thoughts?
