Yup, I have a patch in works wich defers the ndisc_send_ns call in rt6_probe into a workqueue out of the call stack. This should solve the problem. Still wonder if there is a nicer api as to create a new structure and pass the arguments via container_of dereferencing to the deferred function (and I don't think async calls are useable there).
