The "region overlap" problem in the L4/Fiasco hello example

[chenggh]

Hi,everyone:
     When I boot the hello example in the L4/Fiasco. there is a "region 
overlap" in the booting information.  I don't why it could be like this. The 
grub configuration and the error information is following:

Grub:
	title fiasco_hello_new
  	kernel (hd0,1)/boot/fiasco_hello_new/bootstrap -comport 1 -serial
 	 module (hd0,1)/boot/fiasco_hello_new/main -nokdb 
  	module (hd0,1)/boot/fiasco_hello_new/sigma0
  	module (hd0,1)/boot/fiasco_hello_new/roottask
  	module (hd0,1)/boot/fiasco_hello_new/hello
