Not sure why you get that error. Did you apply the proper patch to the proper kernel source? The last good rt kernel that I have used is 2.6.23.1-rt5. I already have the patched source available here should you care to try it.

So, I tried compiling once more, without result. Here's what I do:
1) Get kernel source
2) Patch it with RT
3) Compile kernel
4) Install kernel
5) Restart computer and chose new kernel on boot time
6) I do install NVIDIA drivers (without any problem) [m-a a-i nvidia]
7) I restart computer once more
X.org doesn't start - I get only black screen
What is wrong? Is realtime prempt patch x86 only? Or there's something else?

I don't use any of these (rungetty r0xx). In kernel 2.6.25 from repositories, NVIDIA drivers are working just fine, only when I compile my own kernel they doesn't workmzilikazi wrote:orCode: Select all

I'll give it a try, thank you! (:mzilikazi wrote:]I always thought it easier to build the nvidia module against your new kernel before booting into it. To do this, you must be in the same dir as your kernel source. See the bottom of the howto for that.
For those interested in the bootsplash ....

Good luck...I am using it.

Hi and thanks for updating this guide..
I am trying to build 2.6.25.4 realtime kernel with rt6 patch.
I am building 32-bit kernel on dual-core 64bit system (already got a 64bit partition with working rt kernel).
I have tried several times but cannot get any modules built. When I boot into the new kernel it boots ok but lsmod shows no modules.
I am running export CONCURRENCY_LEVEL=2 before any make commands and following the howto word by word.
Any ideas?

One way this could happen would be if you had built all of your required drivers directly into the kernel and not as modules.Scoop wrote: When I boot into the new kernel it boots ok but lsmod shows no modules.
Are certain pieces of hardware failing?

Sound is not working with compiled rt6 kernel but is working with 2.6.25-2 kernel from sid.
But both kernels see my iPod automatically when I plug it in via USB.
lspci sees the soundcard.
What I did:
installed recent lenny businesscard iso and installed base system over net.
Changed lenny to sid in /etc/apt/sources.list
Ran aptitude update, dist-upgrade.
Installed Desktop Environment with tasksel.
Then followed your excellent howto, but used rt6 patch as that is most recent.
Possibilities:
*tasksel did not get all necessary packages, eg. basic pkgs like eog and gedit were not automatically installed by tasksel. But I am running tasksel 2.74.2
*The mirror I'm using doesn't have all packages. (I tried another mirror, no change.)
*The 'make modules' part of make-kpkg is failing.
I added stable and testing entries to sources.list and updated and upgraded but no extra (missing) packages were found.
