ahh - found it !
that`s not an uml bug but a devfs issue.

http://linuxfromscratch.org/pipermail/lfs-support/2002-August/009320.html
gave me the hint.

suse9.1 doesn`t use devfs - but my uml had devfs compiled in and it was
switched on during boot.
so - it`s important to make sure, that devfs isn`t active (devfs=nomount) in uml 
on distro`s which don`t use devfs.

if you need devfs and experience that issue, it can be workarounded, though:

ln -snf /proc/self/fd /dev/fd

roland

Hi !
I`m getting the following errors with uml 2.6.6 (2.6.4 had that, too) and suse9 rootfs during boot (see below).
can anybody give me a hint, what`s the problem, and how to (probably) fix this ?
networking basically works - but i have to setup the defaultroute manually afterwards and soooo many errors during boot really don`t
give a good "feeling" :)

regards
roland
