Keyboard not working at mountroot prompt; 6.1-R

[Georg-W. Koltermann]

Hi,

today I noticed the keyboard is not working when I boot with a wrong
entry for the root fs in /etc/fstab.  The kernel loads ok, then
announces that it is not able to mount the root fs, and prompts for a
new root fs.  At that point I can press whatever key I like, nothing is
accepted; not even Ctl-Alt-Del.

System is IBM T42P laptop, FreeBSD 6.1-Release.

Is this known?  I remember vaguely having read something about kbdmux
problems some time ago.
