Hi Heiko,

2.6.14 or former kernel had an issue - when the auto-negotiation
took long time, DAD NS was lost.  This issue looks like that issue.

 Ref. [IPV6] Run DAD when the link becomes ready.
   http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=c5e33bddd3c798f681f8f3027270127be6b61a3b

However, 2.6.15 should not have this issue.
To make sure, could you try to let the auto-negotiation off?

Thank you,
