Dear Mr. Gerum,
We have followed following steps to install xenomai patch on UBUNTU. After
repeated attempt in multiple system, still we are facing same issues.
We have used following version for installing xenomai patch on UBUNTU
1. linux Kernel: linux-2.6.32.18
2. Xenomai patch: xenomai-2.5.4
3. Operating System: UBUNTU 10.04
Following Steps have been followed to install xenomai patch on UBUNTU:
1. Copied the linux tar file into /usr/src
2. Copied the xenomai tar file into /usr/src
3. untar the linux and xenomai file
4. cd /usr/src/xenomai-2.2.0/scripts/prepare-kernal.sh and appropriate linux
directory, architecture(i686) and adeos path were given
5. Make a copy of the .config file of the running kernel in the present
directory.
6. Next ran make menuconfig and made the following changes:
I. Selected Processor and feature -> Preemption Mode
II. Power Management option
a. Disabled ACPI.
b. Disabled Frequency Scaling
7. Build the Kernel(make command)
8. copying the image of the kernel to the boot folder
cp arch/x86/boot/bzImage /boot/vmlinuz-2.6.32.18-xenomai-2.5.4
9. At last, I tried to reboot the system in the new kernel image and found the
following issues:
dev_node is not supported in this system.
IO APIC#0 ID is already in use.
PnBIOS: Unable to get nod information.
Sdb1 could not mount because of the unsupported optional Feature.

A few hints:
- that question from mainstream x86 distro users is definitely a FAQ on
our mailing list. Did you have a look at the mailing list archive, to
find common answers to this problem?
https://mail.gna.org/public/xenomai-help/
- Did you read the TROUBLESHOOTING file at the top of the Xenomai tree
and on our website?
http://www.xenomai.org/documentation/xenomai-2.5/TROUBLESHOOTING
- Did you read this FAQ?
http://www.xenomai.org/index.php/FAQs#Tips_and_tricks_setting_up_your_x86_kernel
- Do you mind sending a bit more information than "my system hanged up"?
Any boot log to share? A kernel config file maybe? Did you disable the
quiet boot option to see kernel messages while booting? Are there any
messages at all? Our mail archive is full of advices regarding the way
to troubleshoot a boot issue on x86, make sure to read them first.
- Please always provide a meaningful subject line, so that people having
the same issue could later find and reuse the information from that
thread. "HELP" - particularly on a list called xenomai-help - does not
qualify, at all. Because it could be seen as a waste of time by your
recipients, it may even be counter-productive, and tends to bury your
mail.
- Please stop posting to xenomai-help-owner, really. This address is for
sending requests related to your mailing list subscription, only.
- Please do not re-post the very same question multiple times within
less than 24 hours. It makes no sense; you can check that your previous
message did arrive in our mail archive, so no need to spam the list with
a rehash of your previous post. If people did not answer you yet, it may
be because: 1) you did not provide sufficient input for them to think
about your issue, 2) they don't have time to answer you at the moment,
3) they don't care, 4) they don't know, or any combination thereof.
