hi!

Yes, it is known defect, and I’m searching for cause; the issue is with /boot/loader and BIOS text mode (unfortunately I have the usual ‘but it is working for me’ case). For workaround, you can try to either: 1 (blind) press esc to get out of boot menu, then enter: vbe on; another option is to add hw.vga.textmode=“0” to loader.conf.

Sorry for confusion,
