Try adding the following to /boot/loader.conf then reboot and see if the "excessive repeat" behaviour changes: hint.kbdmux.0.disabled="1" It would also help if you would state exactly what brand/model of keyboard is used. Yes, believe it or not, it matters. dmesg output would be helpful in this case. -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
