Oops from netlink or what?

I reported this previously and it was verified.

Is this a bug in netlink or what?  Who should I report this to?

Original Oops report:

Thanks.

Can you reproduce it? Can you try with latest bk snapshot? if the
problem still exists write to netdev@oss.sgi.com.

Consistently with 2.6.4 and 2.6.6 with the linked tc-graph.pl script.
