First one is again in NetworkManager process (just after loging in to gnome, exactly like previously), and again NetworkManager process is killed. And again restarting NM manually make it happy (and works without further problems). So indeed it looks to be problem with netlink, because netlink_recvmsg is common call here. Second one is also in netlink, but process is this time ip, and message is [ 9136.204156] BUG: sleeping function called from invalid context at kernel/mutex.c:271 full stacks bellow.
