But this patch is not in 2.6.35 and therefore cannot make the
difference Eric sees (belives to see) between his modified 2.6.32 and
2.6.35.

Also, this patch, if I understand that correctly, only changes bridging
and in my scenario bridge.ko (have it as module) was not even loaded,
so applying this patch should not make any difference for the bug I
see, or do I overlook something?

So, I guess, your answer was general information to Erics question what
changed with ipv6, not related to that bug we seek in particular?
