While I'm not at home to do the other things you've mentioned: I don't even have time to run ifconfig - I've commented out the lines enabling ndis, if_ndis and rtl8180_sys in /boot/loader.conf. I just run kldload rtl8180_sys the kernel panics automatically.Received on Tue Sep 22 2009 - 19:49:28 UTC
