>Description:
If the root entry in /etc/fstab is wrong, the kernel prompts for the root
device after loading, right before it wants to mount root.

In 6.1-RELEASE I do get the prompt, but cannot type anything.  The keyboard
is completely unresponsive, not even CTL-ALT-DEL, nothing.

System is IBM T42P laptop.
>How-To-Repeat:
Put an incorrect disk as / mountpoint into /etc/fstab; then try to reboot

Be sure to have another bootable medium ready, otherwise you will be stuck :-)
