What I've given is just about all the code (I know, famous last words: "Nothing else could be wrong!") On a freshly booted system, the code hangs just by doing the socket, bind, and ioctl calls. However, I was a bit premature in mailing to the kernel list. This problem only occurs with a kernel patched to include Linux-ATM support, and not in the standard distribution kernel. The process hangs when using a socket bound to an IP-Ethernet and IP-ATM interface. If someone wants some info in helping to track down the uninterruptible sleep processes, then I can easily reproduce that problem.
