problem during the boot

[Lorenzo Micheli]

Hi, i've just installed debian GNU/Hurd and i passed this to grub:

root (hd1,0)
        kernel /boot/gnumach.gz -s root=device:hd2s1 --
        module /hurd/ext2fs.static --readonly
--multiboot-command-line=${kernel-command-1}

and it seems start correctly but when it loads the modules, it die
without crash messages! the last messages is:

2 multiboot modules
/lib/ld.so.1 /hurd/exec

Do you have a proposal for what to do now?
