Installed on Ubuntu 10.04 tries to start and then

Rick,thanks for the response
I have run the latency test and it's OK.I read that you specify thread and my results are:

I have a double core machine
I have OpenGL driver for a graphics card
EMC doesnt work from the LiveCD
Latency test works fine from the LiveCD and from installed Ubuntu 10.04
The real time kernel has loaded -Linux andrey-desktop 2.6.32-122-rtai #rtai SMP Tue Jul 27 12:44:07 CDT 2010 i686 GNU/Linux

Hello Andrey,

If you have not already you may want to take a look here...

Rick,thanks for help.
I have not resolved my problem . I turned to the two links above, fulfilled all the recommendations contained there.
I'm not positive yet.Here is my RTAI latency calibration:

It seems to me. That here everything is OK...Now I'm at a dead end .

Andy,
I've tried all the user interfaces with simulation config, but the result is negative(
I have two comments:
1)Sometimes the program runs (very rarely)
2)EMC (with Lucid) is installed on a laptop Acer Aspire 5112

Perhaps the problem in the hardware...

Andy,
I read the link you specified. All RTAI components and modules are loaded .

andrey@andrey-desktop:~$ ls -l /dev/RTAI_SHM
crw-r--r-- 1 root root 10, 254 2011-07-13 18:31 /dev/RTAI_SHM

I also changed the file /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash lapic"

The result remains the same.

Truth be told from what I and others have experienced some machines run fine on 8.04 but not on 10.04
If you do not have a compelling reason to use 10.04 at this time you might consider staying with 8.04 until the magic bullet for 10.04 is found.

Rick,
I also thought about it. Let's wait for better times to 10.04, even more 8.04 with EMC work fine.
I just wanted to try a new OS.
