           Summary: assertion failed at net/ipv6/addrconf.c, plus halt fails
    Kernel Version: 2.6.9 & 2.6.10, kernel.org tree
            Status: NEW
          Severity: normal
             Owner: yoshfuji@linux-ipv6.org
         Submitter: jgoerzen@complete.org


Distribution:
Hardware Environment: Alpha 164LX 21164a 600MHz
Software Environment: Debian unstable
Problem Description:

During bootup, I am getting multiple instances ofitems like this, typically when
a daemon starts up:

Jan 12 17:23:38 erwin kernel: RTNL: assertion failed at net/ipv6/addrconf.c (1992)

Trace shows:

The system appears to function normally after bootup.  

However, when it comes time to halt the system, I cannot.  It stalls with:

unregister_netdevice: waiting for sit1 to become free.  Usage count = 1

This machine is acting as a firewall.  I have two Ethernet devices in it; one
for the outside and one for the inside.  The outside speaks only IPv4.  Inside
speaks IPv4 and IPv6.  IPv6 is routed to the outside via sit1, using the public
6to4 router address.

I will attach dmesg logs, ksymoops output, configurations, etc.

This behavior was observed on both 2.6.9 and 2.6.10.

Please ask if there is any other information you would need to resolve this
problem.  I am quite happy to provide anything that may be of use.
