Hi, Sometimes ago I saw a post on the list which indicates that unregister_netdevice on vlan interfaces made some problem for restarting the network service. Today I experienced the problem again and following Ben request I tried to unload the iptables module from the kernel to see if it is related to the iptables but it is not. I have already the problem on 1 of my VLAN interfaces and it is still giving me this message on the messages : Dec 2 02:39:49 SDT-GW kernel: unregister_netdevice: waiting for eth0.102 to become free. Usage count = 1 Dec 2 02:40:20 SDT-GW last message repeated 3 times Dec 2 02:41:30 SDT-GW last message repeated 7 times Dec 2 02:42:40 SDT-GW last message repeated 7 times Dec 2 02:43:41 SDT-GW last message repeated 6 times Any other idea or test to findout the problem ?! --- Regards ================================================================= / Seyyed Hamid Reza / WINDOWS FOR NOW !! / / Hashemi Golpayegani / Linux for future , FreeBSD for ever / / Morva System Co. / ------------------------------------- / / Network Administrator/ hamid@xxxxxxxxx , ICQ# : 42209876 / ================================================================
