Check your boot sectors. boot0 is shared between the slices, so that’s less of a concern, but boot2 is specific to each slice. You can force a serial console by writing “-P“ to /boot.config (if not already done). It helps if you tell the kernel specifically to use a serial console (as well): boot_serial=yes hw.uart.console=“io:0x3f8” boot_multicons=yes I have found that with vt(4) it’s pretty much impossible to not have it claim the console. I haven’t figured out why... -- Marcel Moolenaar marcel@xcllnt.net [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iQIcBAEBCgAGBQJV5H7CAAoJEIda8t8f0tjjgn0P/jZ2Y2XsNQVuvRtKTwOijSMN gyqmoVpYeJKVIz88i5RXaNFaM5R+I4fUXSqkGHnzzCl59RTM6q1xkkfFL52ArEsP Er9Dw00WVPJzBQSeKzfe1+t1AxAlZEnH/U2FIQBDjb4T8CWN3lNuTeyHjzp+TBV/ u2uOT/N9atToKPLAWpmC5WseVW37frpAsubBb9xMsG4bUDSY+wLYcJENbcAx+3X3 7WRpmcXgIY6uiFITbNUmu6SBgsJqIAaAcSZkS9JFhTX6WiOtL2fMJlYedNnZzKMf 8flQE3wEt7csSjIHOzrEo4yA6rTqhVmnH8hEuTdymrTCOuUXi3hdZkqaXrLCxBDg k3JqpGYPG0nQvN48ST0+dm4ykd4W1uPyaeX2KkbRqTQaFq3Vdf4KYjuulxqtwwri KnxLNOpd++/yquhCq+a6QZ9/u7vgnMIO0U0zQm39xr3CWizJ7B2md4OTEQ6XNSaV GSpZM8OKJNCXewhp9BFZ+ZXGQoO5xS+KnmB6GKq4F1saYw+kziiSZ2DtDFxIBBAq KAB9ZtRv6XMsVhj1MW8vlXaovnIg7q9zrvUwhXv54f/rapG4HhnfRbKDJW9O768z F1FTIYOHzXPpqxmOw6kJfw3vUExH2Qih6DCaxx2WxYwV79SB2f7rp4MlCEgC4+8t URqI26ZCfCoDwoaMBr0+ =o1aB -----END PGP SIGNATURE-----
