I'll try to compile "clean" kernel, without rt patch and see if that makes any different :)

Hi,

Is it possible to do this with another kernel?
(I want to have is good but stable...., using testing).

What are the commands if you don't want a bootsplash?

Sure, you just need the appropriate realtime patch to match the kernel version you wish to build.

Just skip the bootsplash patch of course! ;)

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.

patched source? So I can skip these commands?

Code: Select all

wget http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.tar.bz2
wget ftp://ftp.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.24-rt1.bz2
wget http://fatcat.ftj.agh.edu.pl/~przyboro/other/bootsplash/bootsplash-3.1.6-2.6.24.diff
unp linux-2.6.24.tar.bz2
cd linux-2.6.24
patch -p1 <../bootsplash-3.1.6-2.6.24.diff
bzcat ../patch-2.6.24-rt1.bz2|patch -p1
cd ..
mv linux-2.6.24/ linux-2.6.24-rt1
When I skip this and start I'll get:

Code: Select all

:~/kernels/linux-2.6.23.1-rt5$ make menuconfig
make: *** Er is geen regel om doel 'menuconfig' te maken.  Gestopt.

Use wget to fetch the source.

Code: Select all

wget http://www.hotlinkfiles.com/files/646109_jx15j/linux-2.6.23.1-rt5.bz2
unp linux-2.6.23.1-rt5.bz2
cd linux-2.6.23.1-rt5
make oldconfig
make menuconfig
Then continue on as usual.

It's not a quickie build for me :(

When I want to unpack the file I'll get:

Code: Select all

bzcat: Compressed file ends unexpectedly;
        perhaps it is corrupted?  *Possible* reason follows.
bzcat: Success
        Input file = linux-2.6.23.1-rt5.bz2, output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

I just downloaded and extracted the tarball and it was fine. Did you use wget to download the file or a web browser? wget is the preferred method. Also you can check the md5sum:

Code: Select all

md5sum linux-2.6.23.1-rt5.bz2
Result should be:

Code: Select all

0d4b48f1a0890d2bccd58ad4eb862980  linux-2.6.23.1-rt5.bz2
Then just extract it

Code: Select all

tar xjvf linux-2.6.23.1-rt5.bz2

Can I add that I like running the process in an X environment when I compile a kernel. Thus I use sux - and make xconfig and then load the relevant config-xx.x.x.x.x from /boot.

typically how long does it take for a rt patch? I see 2.6.24.5 has no rt patches.

Looks like it was skipped but I see that 2.6.24.7 & 2.6.25.4 just showed up

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
8) 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 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.

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 work :(

I'll give it a try, thank you! (:
