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.

The module is correctly loaded : Loading kernel... /boot/kernel/kernel text=0x1b4 text=0x68d638 text=0x1c84f0 data=0xb4070 data=0x0+0x258000 syms=[0x4+0xa5ab0+0x4+0x119fd4] Loading configured modules... /boot/kernel/if_rtwn_usb.ko text=0xb960 text=0x62c0 data=0x2cc+0x3b syms=[0x4+0x3570+0x4+0x293f] /boot/entropy size=0x1000 /etc/hostid size=0x25 Using DTB provided by EFI at 0x87f00000.

Kernel args: (null) ---<<BOOT>>--- But it isn't loaded anymore after booting : root@bbb:~ # kldstat Id Refs Address Size Name 1 1 0xc0000000 d23a8c kernel I don't think it has to do with the switch to GENERICSD, there is (at least shouldn't be) any difference between the old BBB image and the GENERICSD one. -- Emmanuel Vadot <manu@bidouilliste.com> <manu@freebsd.org>home | help
