CPU=x86_64,
Linux version 2.6.24-23-generic (buildd@crested) (gcc version 4.2.3
(Ubuntu 4.2.3-2ubuntu7)) #1 SMP Mon Jan 26 01:04:16 UTC 2009
scanModem update of: 2009_01_19
Some modem drivers can only be used in 32 bit modem on x86_64 systems,
while some others are competent on x86_64 Systems. Cases are:
1) http://linmodems.technion.ac.il/bigarch/archive-seventh/msg03119.html
for the snd-hda-intel audio+modem driver. Also applicable to AC97 modem
controllers.
In both cases, 32 bit libraries must be installed to support the
slmodemd helper having a precompiled 32 bit component.
2) For USB modems using the slusb.ko driver. 32 bit libraries must be
installed to support the slmodemd helper having a precompiled 32 bit
component
3) The hsfmodem and hcfpcimodem drivers for Conexant chipsest modes are
x86_64 competent.
There are no blacklisted modem drivers in /etc/modprobe* files
Potentially useful modem drivers now loaded are:

Modem interrupt assignment and sharing:
===================================
The modem interrupt (IRQ) is 255 . IRQs of 0 or 255 are not functional!!
The CPU cannot control the modem until this situation is corrected!!
Possible corrections are:
1) Within the boot up BIOS, change from a Windows to a non-PNP/Other
Operating System type.
Instructions for accessing BIOS are at:
http://linmodems.technion.ac.il/resources.html within: Additional
Resourcces.
2a) Add an option "pci=routeirq" to the kernel boot up line.
Here is an example paragraph from /boot/grub/menu.lst :
title Ubuntu, kernel 2.6.15-26-686
root (hd0,6)
kernel /boot/vmlinuz-2.6.15-26-686 root=/dev/hda7 ro
pci=routeirq
initrd /boot/initrd.img-2.6.15-26-686
savedefault
2b) Same as above, but use "pollirq" instead of "pci=routeirq".
3) Within some BIOS setups, IRQ assignments can be changed.
4) On non-laptop systems, moving the modem card to another slot has
helped.
5) Sometimes upgrading the kernel changes IRQ assignment.

----------------end Softmodem section --------------
LSI/AgereSystems produces several modem chipsets produces several
chipsets supported by
an agrsm software packages. This includes some modems identifiable by
their PCI IDs and
others requiring ALSA diagnostics to recognize the chip, such as the
11c11040 chip hosted
on the Subsystems of many High Definition Audio cards.
There are support packages at
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/
The agrsm-tools package supports driver autoloading, but does not itself
contain drivers.
For Debian/Ubuntu related distros, there are a few kernel-version
specific packages:
agrsm-2.6.27-7-generic_2.6.27-7.14_i386.deb
agrsm-2.6.27-9-generic_2.6.27-9.14_i386.deb
are respectively for systems with Ubuntu 2.6.27-7-generic and
2.6.27-7-generic kernels.
agrsm-ubuntu8.04.1-2.6.24-19-generic.tar.gz is for 2.6.24-19-generic
kernels.
The currently used agrsm code is from updates at
http://linux.zsolttech.com/linmodem/
see an example at:
http://linmodems.technion.ac.il/bigarch/archive-eighth/msg03863.html
Read the Modem/DOCs/Agrsm.txt
The AGRSM code package is not yet functionally on x86_64 systems,
except in Intel architecture
emulation mode. This is because there is a 32 bit encypted component,
precompiled at LSI/Agere Inc. It cannot be functionally linked with
other 64 bit components compiled on a x86_64 system.
When/if LSI Inc. provides the encypted component in 64 bit format,
service will be possible.
However if a 32 bit version of Linux is re-installed, the modem will
likely be serviceable,
through there will be some overall performance loss.

Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.2.3
and the compiler used in kernel assembly: 4.2.4
The patch utility is needed and is needed for compiling ALSA drivers,
and possibly others.
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.2
linuc_headers base folder /lib/modules/2.6.24-23-generic/build
However some compilations and executable functions may need additional
files,
in the FileNames.h (so called kernel "h"eaders) collection installed
in /usr/include/ .
For martian_modem, additional required packages are needed. The also
required headers of package libc6 are commonly installed by default.
Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev
packages, for kernels 2.6.24 and later versions.
In not included on your install CD, search for them at
http://packages.ubuntu.com
or comparable Repository for other Linux distros.
When compiling ALSA drivers, the utility "patch" will also be needed.
If a driver compilation fails, with message including some lack of some
FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include.
The minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev
If an alternate ethernet connection is available,
$ apt-get update
$ apt-get -s install linux-kernel-devel
will install needed packages.
For Debian/Ubuntu related distributions, run the following command to
display the needed package list:
Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:
$ sudo dpkg -i *.deb
