If you could now confirm 44ca7478d46aaad488d916f7262253e000ee60f9 as not causing the freeze we have finally isolated the exact commit that is causing the freezes.

Confirmed. 44ca7478d46aaad488d916f7262253e000ee60f9 is in use now for ~ 3 days and no freeze has occured. That would support your assumption. And I think, it's a very likely one.
