touchpad+sound+shutdown not working in knoppix 3.8.1

In knoppix 3.7 everything works, but in the new 3.8.1 there is no sound (in the boot it still detects the same audio, but doesn't enable it), the touchpad doesn't work properly (sometimes it moves well, sometimes it stops, sometimes moves too fast, with external usb mouse works ok, so not big problem) and mos important, the shutdown always stops at the eth0. Also, when I try to change the kismet config file it works the first time, then it appears to become read-only and I can't change it again. Can someone help me?
