Hi everybody,
this is my first post in this mailing list :-). I've recently moved back
to iran and have to connect to the internet using a slow dialup
connection ( Damn, I miss the broadband internet connection I had in
germany :-( ). I use gentoo linux and am currently running the 2.6.26er
kernel. I also have the 2.6.25er kernel at disposal. I tried to get my
agere modem** (11C11040 HDA) up and running following this guide:
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/HOWTO-Agere-11c11040-HDA.html
but had no luck so far. The 2.6.26er kernel fails completely, i.e. the
modem kernel modules (agrmodem and agrserial) do compile properly but
using them to connect exposes a kernel bug. The kernel logs say this:
ep 21 20:25:22 [kernel] agrmodem: module license 'Proprietary' taints

I've used both the Alsa 1.15 and the 1.16 kernel modules. I am using the
In-Kernel drivers shipped with the kernel (on gentoo you can also use
the alsa-driver package with slightly more up to date drivers) and the
version reported is 1.16. I've nonetheless tried the 1.15er drivers to
make sure they also don't work. Using the 2.6.25er Kernel I get a little
farther. Since the 2.6.25er Kernel - I am talking about the gentoo
patched kernels that contains a number of patches and not about the
vanilla kernel here - ships alsa-1.16pre it gives me the "No stream"
error mentioned on the Howto. Thus I've used the 1.15er driver and I can
at least query the modem using Kppp. Trying to connect with the internet
using wvdial or Kppp however results in a full scale Kernel-Panik :-(. I
want to make sure these issues are related to the 2.6.25er and 2.6.26er
kernel before going through the hassle of downloading the 2.6.24er
kernel sources in the hope of having more success with it. Can anyone
tell me about the state of the drivers regarding the newer versions of
the linux kernel I mentioned above?
Thanks in advance,

Completed candidate modem analyses.
The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.3.1
and the compiler used in kernel assembly: 4.3.1
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.3
linuc_headers base folder /lib/modules/2.6.26-gentoo-r1/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
