This makes me think that this uncommon huge delay is the culprit. I checked this with some snapshot thats I had installed already. The issue seems to have been introduced together with the switch to GENERICSD. A GENERICSD 13-CURRENT from end of December showed this issue already, while a BBB-specific snapshot (from November 2020) that I had installed on another BBB works as before by loading the modules in /boot/loader.conf. > >>> > >>> I don't mind to load the modules by the way of the kld_list directive in /etc/rc.conf.

And in addition loading the if_rtwn_usb.ko module and its dependcies manually also takes now significantly longer compared to a manual load on the BBB specific 13-CURRENT from November. Perhaps something has been changed in the dependency resolver. > Fixed in 0f2434ea000e Thanks for reporting. -- Emmanuel Vadot
