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.
