Default Howto recompile kernel package with a different Timer Frequency

Hello list,

I am looking for a howto for recompiling the original ubuntu kernel
package with another Timer Frequency, in this case 250Hz instead of
100Hz. I wasn't able to find a useful document yet. I hope that someone
can give me a hint, a link or point me in the right direction.

Thanks in advance.

Regards,

Jan Marquardt

Currently it isn't valid.
I've tried to recompile kernel - and got some linking errors. (see bug
https://bugs.launchpad.net/ubuntu/+source/linux-meta/+bug/237528).

If anybody succeeded with rebuilding ubuntu kernel from source
(2.4.26-18/-19) please, let me know "how".

Good luck!

Hm, the last time I recompiled the kernel was on Gutsy. It worked then
as described in the document.

Since I haven't tried it myself, just a wild assed guess: does the
version of the installed linux-headers-... match the version of the
kernel you're trying to build?

of course.
I've tried both ways: old (make config & make...)
and "new" (debian/rules....)

Recently I've installed Gentoo on my laptop - there wasn't any problems
with kernel. But their kernel is much more like vanillas one.

I just recompiled my kernel (Changed to 64GB and Core2) I used this
site:
http://www.candelatech.com/oss/ubuntu-live-notes.txt
as a guide. You do need to make some changes while you go through the
guide but it's not difficult.
I tried the wiki page first but didn't find it to be that helpful.

Hardy 64-bit
$ uname -r
2.6.24-18-generic

I just did a
$ apt-get source linux-image-$(uname -r)
$ AUTOBUILD=1 NOEXTRAS=1 fakeroot debian/rules binary-generic
and it worked flawlessly (I didn't install any build-dependencies
because everything needed is already installed on my machine).

Just to be sure: you noticed that the package names for the kernel
source and build dependencies for Hardy are different from previous
versions?

Are you really sure? Since 2.6.21 or so, the linux kernel uses dynticks
and it is my understanding that the old frequency measurement does not
really mean much anymore. Try http://www.google.com/search?q=dynticks
for more

This is the main difference. You compile 64bit version.
And error's reason is absence of some objects in 32bit version, which
present in 64bit and some other arch's.

I've tried to build it again. With dependences and others... Same result.

No, it isn't. I just compiled the 2.6.24-18-generic kernel on a fresh
install of 32-bit Hardy server following the steps in the wiki article
and it worked flawlessly.
