Hello,

I made a new try.

First, I have installed an unpatched Ubuntu 8.04 LTS (64bit). This 
works, without errors! In next step I installed EMC2 (by using the 
script). But my pc did not start up with the RTAI- Kernel:
--------------------------------------------------------------------------------------------
Loading, please wait....
Check root= bootarg cat /proc/cmdline
or missing modules, devices: cat /proc/modules ls /dev
ALERT! /dev/disk/by-uuid/ffd2f6b7-dbe1-4609-bf48-90830846ec01 does not 
exist. Dropping to a shell!
BusyBox v1.1.3 (Debian 1:1.1.3-5ubuntu12) Built-in shell (ash)
Enter 'help' for a list of built-in commands.
(initramfs) _
Kernel dyesct mapping tables up to 100000000 @ 8000-d000
-------------------------------------------------------------------------------------------

It seems that the partition can not been found by UUID, but the 
"ubuntu"- kernel starts with this config:

----------------/boot/grub/menu.lst------------------------------

------------------------------------------------------------------------

I have tried also to substitute the UUID by "root=/dev/sda2", where 
ubuntu is installed.

I use this hardware setup and patitioning:
----------------------

Note: /dev/sda1 is swap!

Mainboard: MSI 785GM-E51 (AMD 785G North Bridge, AMD SB710 South Bridge 
(SATA devices are connected to this chipset!))
RAM: 2GB

What can I do to make it work? Please help........
