I booted 8.0-BETA2 from the same hard drive install on about 15 machines, and saw this problem on four of them, all identical motherboards. In this setup, I had "-D" in /boot.config "console-comconsole" in /boot/loader/conf ttyu0 enabled in /etc/ttys I was then accessing them over the serial port. When the machine had booted and was showing the "login:" prompt, sometimes input would be ignored from that point, and other times it would allow me to enter "root" but would hang on the enter. Once it had hung, sometimes hammering the keyboard would bring it back, but the only reliable way of getting it to recover was to have the kernel print something out. Luckily, the three LOR's often printed a minute or so after boot would do this, but unplugging/replugging (say) a USB keyboard so that the detection lines were printed would also free things up. I don't know if that gives any clues as to where the problem lies. Gavin
