Odd occurences with udev and wireless networking

Hi

I recently compiled a new kernel.

I have the following in my /var/log/syslog :

Aug 8 11:06:18 host1 udevd-event[31938]: rename_net_if: error changing net
interface name wlan0_temp to eth1: No such device

As a result, I am left with a wireless device named wlan0_temp instead of
eth1 that it ought to be. This screws up my firewall scripts, I think (a
restart of iptables guarddog throws up a lot of complaints).

In an older kernel, I get the same message above, and have :

..... rename_net_if: error changing net interface name eth2_temp to eth2: No
such device

I have both hostap_cs and orinoco drivers loaded. Could that be throwing off
the rename in some fashion ? If so, how do I blacklist hostap drivers ?

What could be going on ?

Thanks.
