Hoerdt,
        I ran all of your test cases successfully on my i386 machine,
before I sent the patch. Can you send me the register dump and stack
backtrace you got? If you don't have a serial console set up on the
machine, some people have used a digital camera to create a jpg
image of the screen, or a transcription of what you see would be
helpful.
        Also, the only portions you should really need are the
loop in ip_sock_mc_join() and the EADDRINUSE check in ipv6_sockglue.c.
You might try applying just those portions and see if you still
get it. My first guess would be a lock issue with the "leave group"
portion, and I'll investigate that some more to see if I can
reproduce it.
