Not sure if related, but something similar has been fixed in 4.2-current already.
This was also the first thing that came into my mind, however, I don't think it is related. VR_STICKHW is only written erroneously during attach, and since my machine runs now for several weeks without any problem, I doubt that the observed stall has something to do with this.Opinions by the vr maintainers? Anything I can do to debug the problem when it occurs next time?
