I can confirm this also happens with a 7260 on 13.1-RC2. I can NOT get it to work on warm or cold boot. I use devmatch_blacklist="if_iwm.ko" However. After login, if I send a service netif restart everything works as intended. I know this is a 7260 and not 8265 / 9560. But thought it still might be useful to know. > > > Thanks in advance!
