Hi Ingo,

Couldn't this just be a more generic Linux kernel issue 
with the combination of ipv6, bridging and ndisc ?

Wouldn't be the first time that a config more common on systems running Xen,
would more prominently expose a kernel bug in the networking stack. 

Have you brought this up on the LKML / netdev mailinglists already ?
