Couldnt find a bug-report or anything like that so I guess Ill just post it here...
I downloaded "crunchbang-10-alpha-01-xfce-i686.iso" and tried it on my dell latitude x300.
The live version worked perfectly, the installation seemed to run fine, but when I booted it for the first time the laptop crashed and restarted as soon as it got to grub.
Now I reinstalled it with lilo which works fine.
So its not really a problem for me but it is some kind of bug.
