WARNING: Device "kbd" is Giant locked and may be deleted before FreeBSD 13.0.
Running FreeBSD CURRENT on a USB only platform with a customised kernel, I see this message all the time I reboot or log console messages: [...] WARNING: Device "kbd" is Giant locked and may be deleted before FreeBSD 13.0. Where does this message come from and what is causing the warning? I tried to identify and eliminate this message, but it seems to be stuck with the USB device/keyboard attached to the system. Any hint? Many thanks in advance, oh pgpKS04T7Chxe.pgp Description: OpenPGP digital signature
