           Summary: unregister_netdevice Prompt and system shell lookup when
                    trying to shutdown vlan
    Kernel Version: 2.6.11-gentoo-r4 i686
            Status: NEW
          Severity: high
             Owner: acme@conectiva.com.br
         Submitter: dcmwai@pl.jaring.my


Distribution: 
Gentoo, FC2, FC3 

Hardware Environment:
Pentium 4 3.0E,
Intel SE7210TP1-E Server Entry Board
512 MB DDR Ram
2x Intel® PRO/1000 Dual Port Adapters

Software Environment:
Portage 2.0.51.19 (default-linux/x86/2005.0, gcc-3.3.5, glibc-2.3.4.20041102-r1)
Fc2 and Fc2 original kernel.

Problem Description:
When Shutdown a Vlan using this command
vconfig rem eth4.1001
The interface will be down (using ifconfig)
However the following error will be prompt on the screen and the log leaving the
shell to be not responding.

Even if "ifconfig eth4.1001 down" is run before "vconfig rem" sill the problem
will be there.
The only way I tested on solve this problem is to shutdown the interface totally.
ifconfig eth4 down

Then the vlan can be removed correctly.

This problem don't happen on the following "special Condition"
1) On another motherboard (Gigabyte GA-81PE1000-G) same NIC on Fc3
1) On eth0 


Steps to reproduce:
1. get a vlan supported NIC, emerge vconfig
2. ifconfig ethx 0.0.0.0
3. create a vlan using "vconfig add ethx nnnn"
4. ifconfig ethx.nnnn aaa.bbb.ccc.ddd
5. remove the vlan using "vconfig rem ethx.nnnn"
6. Wait for the error like the below.
* Motherboard and NIC seem to be a Problem in my case.

unregister_netdevice: waiting for ethx.nnnn to become free. Usage count = 6

I've also open a bug in Gentoo

In the past, IPv6 has often been the problem here.  Are you using IPv6?

What is the hardware/driver for eth4?

Thanks,
Ben

[Ganesh Venkatesan]

I have seen a similar issue without the VLAN module. I was using IPv4.
Happens with 10/100 and 1GbE drivers on Itanium and AMD Opteron
systems. Kernel used was RHEL4 (2.6.9-5.ELsmp).

ganesh.
