I am sure, the problem is the mount of the /dev filesystem.
For boot the MDK9.1 in my native system see /etc/lilo.conf
<<snipp>>
image=/boot/vmlinuz
        label=Linux
        root=/dev/md0
        append="devfs=mount ide0=ata66 ide1=ata66 hdd=ide-scsi"
        read-only
<<snipp>>
In my native system I have to configure "devfs=mount" so linux do mount the
/dev filesystem.
What should I do that UML-Linux also will mount the /dev ?
I have tried --umlargs devfs=mount but this do not work.
