I tried to boot my kernel, and I got :
request_module: runaway loop modprobe binfmt-464c
It's because I played with my /boot/grub/menu.lst and update-grub. In fact I wrote a wrong root= option, and my 32bits kernel was trying to boot on a 64bits distro. Si if you get this error, check if your boot loader is well configurated, and is not messed up with your distros in 32 and 64 bits 
Hope this help.
