What would be the best way to determine why my systems cause so much problems wrt to serial connectivity? Also, what is the best way to debug a kernel over serial when the system on the other end is completely locked?

I have a small 4 port KVM switch from Startech, Is this KVM causing keyboard issues that the keyboard driver cannot interpret properly? Why is this occuring so often? I can usually trigger this if I start using certain key combinations. What also happens is a key will get 'stuck' and then repeat itself until I stop it from repeating the letter. The keyboard is a Microsoft Internet keyboard PS/2 style plugged into the KVM. If you want me to catch any debug output let me know and I will do this.
