For diagnostic purposes, it probably is a good idea to try another
keyboard, temporarily at least. But I have seen an incorrect keyboard
definition cause reboot problems. Another machine I use has a Dell
SK-8125 USB keyboard. This keyboard model has 103 keys. It doesn't
match the default pc105 key mapping. I had reboot problems with it
too, until I set XKBMODEL to dellsk8125. It works fine now.
