Dear Ben , I had this problem also on bond0 device which is eth0 and eth1 bonded device. I thought that it might cause of bonding and that's why I didn't report it before . But the message is as same as darkstar reported. --- Regards ================================================================= / Seyyed Hamid Reza / WINDOWS FOR NOW !! / / Hashemi Golpayegani / Linux for future , FreeBSD for ever / / Morva System Co. / ------------------------------------- / / Network Administrator/ hamid@xxxxxxxxx , ICQ# : 42209876 / ================================================================ -----Original Message----- From: vlan-bounces@xxxxxxxxxxxxxxx [mailto:vlan-bounces@xxxxxxxxxxxxxxx] On Behalf Of Ben Greear Sent: Thursday, July 21, 2005 9:21 PM To: Linux 802.1Q VLAN Subject: Re: [VLAN] unregister_netdevice darkstar wrote: > After all these procedures systems hangs and I was reeboot it. > I hope this information will be useful. Well, I still don't know what is holding the reference. I don't think this is a bug in VLAN code itself, because otherwise lots of people would be reporting it. The only thing I can suggest is to try various different things, including never loading iptables in the first place, and see if you can find the step that causes the problem. If you can find the module that is holding the reference, a bug report can be sent to that module's author. One other thing: Have you tried specifically dropping each VLAN interface before unloading the module: ifconfig ethX.foo down That might possibly help trigger other code to release the reference.
