Try with the cheat code noapm.
Usage: At the boot prompt type: Knoppix noapm (plus other cheatcodes you might need)

thank you Markus,,
It worked partially, it still freezes a bit further... right after it detects my sound card it freezes with no message. I tried with other cheat codes but it still does not work. Would you have another tip for me.

thanks
