The cited snippet from my previous mail was to demonstrate how the resulting hw.uart.console value depends (or rather not :)) on hints. All I have (changed) wrt console is: /boot/device.hints #hint.uart.0.flags="0x10" hint.uart.1.flags="0x10" /boot/loader.conf boot_multicons="YES" boot_serial="YES" boot_verbose="YES" console="comconsole,vidconsole" This setup worked for ages. To isolate this problem I took /boot/loader from my older current machine (also with COM2) to replace it here, and it started to work again. -- wbr, pluknet
