OK Houston, I have a problem.

When I use the install script, everything is ok, it ask me if I want to install xserver-xomap (it ask me each time I make /root/install.....) and seems to install it (unpacking, etc...) ans then download a lot of things, then, "Checking kerner image kerner-rx-34_2.6.21.0-osso71-randr2".So, it ask me if I want to flash. I say yes.
Here is what I have :
Are you ready to flash? (yes/no) yes
