There was recently a fix implemented for a hang issue that seems to be the same thing you are experiencing. The hang was sporadic and hard to reproduce, but specific bridging configurations were prone to causing the hang to be more common (but still not ubiquitous). I am preparing to push a new version of the out-of-tree driver to Sourceforge in the next day or two (working on the Readme for the push). This version will contain the fix for the issue that I believe you are experiencing.
