IPv6 oopsen

[John Goerzen <jgoerzen@complete.org>]

Hi,

I've had some trouble that apparently is tracable to IPv6.  I'm
wondering if anyone else has seen this:

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

Trace shows:

Jan 12 17:23:38 erwin kernel: Trace:

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

FWIW, I submitted it to the kernel bug tracker; see
http://bugzilla.kernel.org/show_bug.cgi?id=4027

Thanks,
John
