It's known that on some machines the serial fails after breaking into debugger and rebooting from there - you need a hard reset in that case. E.g. on PC164. Can you echo foo > /dev/console and/or echo foo > /dev/ttyd0 ? Do you see kernel messages? e.g. tcpdump and look out for promiscuous message. The sio flags are irelevant as the important ones are only checked at kernel start. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
