<WARN> check_one_route(): (eth1) error -22 returned from rtnl_route_del(): Missing link name TLV (errno = Invalid argument)

["The H.W. Group LLC" <the hw group gmail com>]

I use Red Hat Enterprise Linux version 5.3, 32bit on an IBM Thinkpad T60.

I also make use of the ipw3945 driver. 

eth1 is the assigned wireless interface.

These are the versions of NetworkManager that come with RHEL5.3 32bit:
NetworkManager-0.7.0-3.el5
NetworkManager-gnome-0.7.0-3.el5
NetworkManager-glib-devel-0.7.0-3.el5
NetworkManager-devel-0.7.0-3.el5
NetworkManager-glib-0.7.0-3.el5

I am not able to connect to my access point. The Network Manager icon in gnome will appear, show the connection anamation, then when I enter my passphrase, it will connect, then the entire anamation / icon in the information panel will disappear.

This is what tail -f /var/log/messages gives me, during the sequence:
<LOG SNIPPET>

</LOG SNIPPET>


When that <WARN> statement appears, the icon immediately disappears. I have never seen this error before. It is very strange.

I have tried reinstalling all of the rpms, but it makes no difference. I am open to any suggestions at this point. Please let me know if any other information is needed, I will do my best to provide it.
