Hello Bjorn,
Thanks a lot for your reply.
Indeed, I did start with 'make oldconfig'. However, it did not compile
at all the sound driver (snd-hda-intel.ko).
I realized then that there was no .config file inside the package
linux-source-2.6.24.
I expected that the config file (config-2.6.24-21-generic) in /boot were
the one that Ubuntu packagers had used for building the running kernel,
but I quickly discovered that it was not the case, the hda sound driver
being not selected at all.
So, I tried 'make menuconfig', but I probably omitted to select some
other required modules or options.
The problem I am faced to is mainly : how to re-compile and install a
given updated module without changing anything else in the current
kernel release ?
I assume that this is possible since it was done against the Ubuntu
package linux-image-2.6.24-19-generic, the result being shipped in
package agrsm-ubuntu8.04.1-2.6.24-19-generic.tar.gz at
http://linmodems.technion.ac.il/packages/ltmodem/11c11040.
My question is thus: how did people at linmodems.org build the module
snd-hda-intel.ko which resides in the latter package ?

To avoid the config issue, I'd suggest issuing the command 'make
oldconfig' in /usr/src/linux instead of copying the /boot/config file.
This clones the RUNNING kernel's config.
Also, you will likely need to issue 'make modules-install' as opposed to
just copying the snd-hda-intel.ko module, since you are building a
different version than the pre-built- the modules will be incompatible
with your old kernel and modules, so you will need to copy them all, and
likely also do a make and make bzImage... ending by booting the kernel
you've just built.
I'm not familiar with the processes for Ubuntu, as I use SuSE.
If you can get sources for the currently running kernel (with the exact
same patches etc) as opposed to just generic ones for 2.6.24, you should
be able to use these and there will be no need to completely compile the
kernel or reinstall ALL modules.
Since SuSE provides kernel sources patched EXACTLY to the running
kernel, I have no experience with the above, and YMMV.

Hello,
I recently installed with success modules snd-hda-intel.ko, agrmodem.ko
and agrserial.ko on my laptop hp 6720s running Ubuntu 8.04 with kernel
2.6.24-19-generic, thanks to this mailing list (and especially with help
from Antonio Olivares and Marvin Stodolsky).
Since that time I had to upgrade the kernel to 2.6.24-21-generic, in
order to get the wireless link (broadcom) working.
The latter is now ok but not surprisingly the modem does not work any
longer.
As I absolutely need both types of connection (modem and wireless), I am
trying to re-build the sound and modem modules, but could not success
for now.
I installed on the laptop the Ubuntu package linux-source-2.6.24, and
after unpacking it in /usr/src I followed instructions given at
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/HOWTO-Agere-11c11040-HDA.html,
starting at step 1:
1. Check ALSA version: the ALSA driver version is the 1.0.16.
2. Patch file /usr/src/linux-source-2.6.24/sound/pci/hda/hda_codec.c as
stated.
3.1.1: Copy /boot/config-2.6.24-21-generic as
/usr/src/linux-source-2.6.24/.config. CONFIG_SND is not set in this
file: this is not consistent with the 2.6.24-21-generic kernel (in its
initial state), since sound is working...
3.1.2: Change version number in /usr/src/linux-source-2.6.24/Makefile:
EXTRAVERSION = -21-generic
3.2.: make menuconfig : select ALSA -> PCI -> Intel HD Audio, with
support for all HDA codecs listed (every features as modules).
3.3.: make modules
3.4.: Copy /usr/src/linux-source-2.6.24/sound/pci/hda/snd_hda_intel.ko
as
/lib/modules/2.6.24-19-generic/ubuntu/sound/alsa-driver/pci/hda/snd-hda-intel.ko.
3.5.: Reboot
3.6.: Sound does not work any longer. Excerpt of dmesg output:
...
[ 31.627645] snd_hda_intel: disagrees about version of symbol snd_ctl_add
[ 31.627650] snd_hda_intel: Unknown symbol snd_ctl_add
[ 31.627697] snd_hda_intel: disagrees about version of symbol snd_pcm_new
[ 31.627699] snd_hda_intel: Unknown symbol snd_pcm_new
etc.
I suppose that I did some mistake when editing .config (using menuconfig).
What is confusing is that the config file located in /boot
(config-2.6.24-21-generic) does not correspond to the actual kernel
(vmlinuz-2.6.24-21-generic). I attach to this mail both files
/boot/config-2.6.24-21-generic and /usr/src/linux-source-2.6.24/.config.
I attach also the ouput of dmesg.
I thanks a lot in advance anyone who could help me to get my modem link
up and working.
