I updated one of my BBB from an older 13-CURRENT (July 2020) to the = latest 13-ALPHA1 snapshot from Jan, 14th =E2=80=94 = GENERICSD-20210114-7ae27c2d6c4-255938. I had successfully employed an USB-WLAN dongle based on the RTL8188eu = chipset. I only added the following into /boot/loader.conf: if_rtwn_usb_load=3D"YES" By that all dependend modules were loaded automatically in a snap. With = ALPHA1 this doesn=E2=80=99t work anymore. After hours of = troubleshooting, I got it working by adding the following into = /etc/rc.conf: kld_list=3D"if_rtwn_usb" The "Loading kernel modules:" takes apprx. 4 seconds, however, then the = USB-WLAN device is enumerated correctly and it is ready to use. 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. However, the unusual long duration of loading the module = and its dependencies might be an indication for a more fundamental = issue. Please feel free to ask me for doing more tests.=20 Best regards Rolf=
