User-Mode-Linux: Problème de boot

Bonjour à tous,

Je souhaite installer un noyau UML.

Pour cela je prend un noyau 2.6.1 (Systrace oblige), et je suis la
procédure suivante:

make menuconfig ARCH=um
-> Pas de module, et j'active TUN/TAP

bzcat uml-patch-2.6.1.bz2 | patch -p1

make mrproper ARCH=um

make defconfig ARCH=um

make linux ARCH=um

Tout se passe bien (a priori) !

Ensuite j'essaye de lancer mon noyau avec la commande suivante:

./linux umid=debian root=/dev/ubd0 ubd0=debian.cow,Debian-3.0r2.ext2
devfs=mount eth0=tuntap,,,192.168.57.210

A mon grand malheur, le système s'arrete sur
[...]
Universal TUN/TAP device driver 1.5 (C)1999-2002 Maxim Krasnyansky
blkmtd: version $Revision: 1.5 $
blkmtd: error: missing `device' name

NET: Registered protocol family 2

Ca fait 2 jours que je tourne en rond, et je trouve pas.

Je ne sais même pas ce que c'est que ce "blkmtd" ...

Si quelqu'un a une idée !

Merci d'avance de vos remarques.

Ci-dessous, je met le log complet du boot de mon noyau.
