With ALPHA1 this doesn?t work anymore.

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.

I updated my working copy with git pull and verified that your changes made it into my source tree. Then I built a new kernel and replaced the original ALPHA1 kernel from 2021-01-14 by this new one. The rtwn-modules are still not loaded by the if_rtwn_usb_load="YES" directive in /boot/loader.conf. >> >> Best regards >> >> Rolf > > You need to update loader.efi on the ESP partition. Please excuse my ignorance. Do I need to build world for this? Then where is the newly build loader.efi?
