What I found is that the timeout function of syscons (scrn_timeout()) stops getting called after a certain random point during the processing of the rc scripts. It happened most often when the network was being configured. Without this timeout, the console never gets updated except when flushed by a kernel printf. As you noted, input still works fine. Unfortunately, I wasn't able to track this down any farther. Scott To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
