That means, mdev hasn't got the chance to 'restructure' the /dev directory (that is, rename and/or move and/or chown devices). Does 'mdev -s' exist in your /sbin/linuxrc?

That's indicative that it's the kernel doing the populating (tha= t is, everything belongs to root:root). That means, mdev hasn't got the= chance to 'restructure' the /dev directory (that is, rename and/or= move and/or chown devices).

Does 'mdev -s' exist in your /sbin/linuxrc? Can you post your li= nuxrc here?
