WARNING: Device "fb" is Giant locked and may be deleted before FreeBSD 13.0. WARNING: WITNESS option enabled, expect reduced performance. On the Pi3 I see: bob@www:~ % dmesg | grep 'WARNING:' WARNING: WITNESS option enabled, expect reduced performance. WARNING: Device "kbd" is Giant locked and may be deleted before FreeBSD 13.0. WARNING: Device "openfirm" is Giant locked and may be deleted before FreeBSD 13.0. WARNING: Device "fb" is Giant locked and may be deleted before FreeBSD 13.0. WARNING: WITNESS option enabled, expect reduced performance. so the answer seems to be "no". HTH, let me know if I can try anthing else. Both installs are expendable. bob prohaska _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-arm To unsubscribe, send any mail to "[email protected]"
