OK, I finally got things to work. After finally reading UPDATING, I found out that I needed to change my ifconfig_ndis=3D"WPA blablabla" line in rc.conf to wlans_ndis0=3Dwlan0 ifconfig_wlan0=3D"WPA blablabla" I did that without rebooting, things still didn't work, I kldunloaded and kldloaded rtl8180_sys and the kernel panicked again. However, after the reboot everything worked as expected.
