I would appreciate an update to this bug as I am stuck on 10.1.4.
I'm afraid bisecting is still the best bet. To avoid bisecting to a wrong commit, make sure to wait long enough before declaring any commit good.
Also, if you can't test some commits because of the segfault fixed by http://cgit.freedesktop.org/mesa/mesa/commit/?id=cb4ad1368551b64756c7b6e2007... , you can apply that manually for testing those commits.
