I have been using Knoppix for about a year. 6.2 has been great and worked on many different Desktops and laptops I tried with very few combinations not booting or having problems. I have created a 6.4.3 DVD and have not been able to get it to successfully load on any of my test machines (mostly Dell and Toshiba laptops). It seems udev locks up and using noudev gets it to boot but with no functional mouse (USB not Initalized). Debug gives a "tty console not running error". I am only begining to troubleshoot this issue but thought maybe someone else is experiencing the same issue and has a solution and could save me some time. I will post again if i get anywhere with this but for now I am going to continue to use version 6.2.
