Excuse me for the late reply, please. Indeed, on ttyv1 was scroll-lock on. Pushing it one time and pushing 'enter' solved the problem. Thanks for your answer, Ben! On ttyv0, I still see this: root 72794 0.0 0.0 0 0 v0 D<Es - 0:00.00 (login) sys/miscfs/deadfs/dead_vnops.c says it has something to do with with a vnode wich is in a state of change. I have no idea how to fix this, but I suppose the hanging tty will be gone after a reboot, and hey, I still have 9 ttyv's left :) Pieter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
