I note that you don't have {Min,Max}RtrAdvInterval configured.  It 
will take at least this long (the default value) for radvd to detect 
the link has come back up, and possibly the next cycle before it's 
done reactivating the interface.  Make sure that this is not skewing 
your test results.

Could you run a debug output with only one interface configured and 
above in mind?

By restarting radvd, do you mean a complete restart or sending HUP 
signal?  The latter should be enough but the code paths are different.
