"killall -STOP NetworkManager" and now I see that bug is fixed. Sorry for the false alarm. (If anyone would want to reproduce this, NB: be sure to also enable accept_ra* sysctls, otherwise kernel will ignore RAs and bug wouldn't be reproduced on previous kernels too). -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
