So, the problem was related to the cdrom drive (sr0) in combination with the cdr is used for burning the iso. I did some testing on other computers and they all did like the cdr. the strange thing is that it cdr is full readable on the gnome desktop and windows xp only the live cd boot tries to read it and fail after a while, so maybe only some parts are unreable. the cdr manufactor sucks. so I was redownloading the iso now and try another type of cdr and the live cd start up now (it's working) with the following error messages:
[196.401305] I/O Error on device fd0, logical block 0 [234.489599] I/O Error on device fd0, logical block 0 intel_rng FVH not detected "device not found related to acpi"-messages I'm sorry I didn't test the cd before reporting the "bug". Okay, the subject of the bug is wrong now. So fd0 means floppy disk? so, there are no floppy disk on this laptop so this can be ignored!?. So maybe someone could close the "bug" or is this a usefully toshiba satelitte p20 test case info?
