Recompile ubuntu kernel

[Patrick]

Binary package hint: linux-source-2.6.27

Hi there

I've installed the linux-source-2.6.27 package and now I'm trying to recompile it. Why? I want to enable the pci express power savings and want to patch it to enable tux on ice.

To recompile I do: S
make oldconfig
make xconfig
make-kpkg clean
make-kpkg --inititrd --append-to-version=-patrick kernel_image kernel_headers

I've compiled succesfullly various kernels before, but in intrepid I am unable to do it. When I do make-kpkg clean I get this error:

patrick@patrick-laptop:~/Escriptori/linux-source-2.6.27$ sudo make-kpkg clean
exec make -f /usr/share/kernel-package/ruleset/minimal.mk clean
====== making target minimal_clean [new prereqs: ]======

make[1]: Leaving directory `/home/patrick/Escriptori/linux-source-2.6.27'
make: *** [minimal_clean] Error 2

I've tried with a 2.6.26.5 kernel from kernel.org and it works fine. After make-kpkg clean I get this:

patrick@patrick-laptop:~/Escriptori/linux-2.6.26.5$ make-kpkg clean

I believe it's having trouble with arch. The 27 ubuntu kernel outputs ARCH=xen and the 26.5 ARCH=x86_64

Am I doing something wrong or is it a bug?

thanks for you time

Some update: I'm having the exact same problem with the 2.6.27 kernel downloaded from kernel.org.

Hi Patrick,

Where/how did you get the Ubuntu kernel source? I'd recommend cloning straight from the git tree. I'm not seeing any errors on my machine here:

ogasawara@emiko:/tmp/ubuntu-intrepid$ sudo make-kpkg clean
[sudo] password for ogasawara:

The following wiki might also be helpful - https://help.ubuntu.com/community/Kernel/Compile . Thanks.

[Patrick (patrick-voegeli)]

what I did:

sudo apt-get install linux-source-2.6.27
extract the source under /usr/src
cd /usr/src/kernel-dir
sudo make oldconfig
sudo make-kpkg clean

error appears.

Anyway, I just solved it: if I do sudo make xconfig and there untick Paravirtualized guest support, under Processor types and features, save and then do sudo make-kpkg clean it just works, I get ARCH=x86_64 and the kernel compiles just fine.

I still don't understand why it doesn't compile using the same config as the standard ubuntu kernel.

Thank you and sorry

I experience the same bug as Patrick.

I downloaded the kernel source straight from kernel.org, as found here:

http://ubuntuforums.org/showthread.php?t=311158

I've compiled my kernel this way probably two dozen times.

If I uncheck "Paravirtualized guest support," it compiles just fine.

Rather belated response, but I just ran into this bug today while trying to patch wifi for aircrack.

I don't know why this is, but a good solution is to specify the arch with "make-kpkg --arch i386 clean", for example. Just specify any arch name in the source/arch directory and you're good (though you'll want to pick the arch your machine runs on).

[mavant (matthew-avant)]

Typo: "--arch=i386" not "--arch i386".

[Tarek Eldeeb (tarekeldeeb)]

Same problem ..

but adding "--arch=x86_64" did the trick for both clean and make
