How can you tell? The binary blobs may have a glitch, flaw, bug, that makes them write more-or-less random values to random memory locations, thereby inadvertently killing the functionality of other modules (such as the ipv6 tunnel). If the bug happens without the blobs, _then_ one may start figuring out what (non-binary) modules may cause interaction problems with the ipv6 tunnel (or if it's the tunnel module itself).
