I expect this is the failure to join the all-nodes multicast group, in which case the fix has already been posted to netdev. I believe the router advertisements are sent to that, and if the join failed, it wouldn't receive any of them.
I think it's better to add the fix than withdraw this patch, since the original bug is a crash. Details: The IPv6 code passes the "dev" entry to the multicast group incrementer and uses it to dereference to get the in6_dev. IPv4, by contrast, passes the in_dev directly to its equivalent functions. IPv6 joins the required "all-nodes" multicast group in the multicast device initialization function, which due to the fix won't have a dev entry at that time. The patch posted by Yoshifuji Hideaki moves the all-nodes join until after the ip6_ptr is added to the dev. +-DLS - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
