Atl1c NIC Blues No More

[Hyksos]

Hey! Un Québécois Tabarn**!

I can replicate/emulate your problem by basically breaking all css and images file on the apache.

I found a bunch of stuff on the internet including this:

Hello,
As far as I can tell it there is the bug occuring when combination of
sendfile(2) and module atl1c is used. The result of the bug is data
corruption. Examples of data corruption are in attached files:
- orig.txt - the original file, output of command
seq 1 600 | xargs printf '%04d\n'
- apache.dat - result of wget http://the.server/orig.txt -O apache.dat
- sendfile.dat - file sent from the same server using attached program
and netcat

The mentioned server has a multiple interfaces and this problem appears
only on Atheros interface. After spotting the problem on Apache first
I finally nailed it to sendfile function. The problem appears only for files
longer than some specific value. For Apache it was 2600 bytes (I suppose it's
because of headers added by webserver). For my test program the minimal size
of file where the problem appears is 2896 bytes.

I also found a similar problem on Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/slide-webdavclient/+bug/651004
The common factor is Atheros AR8131.

Maybe an updated driver or kernel or both could solve it, I read it too but will leave that in your hands.

And BTW in retrospect in means that posting full details of your system when asking a question, even if you think it has no possibility of being a factor IS key.

If you guys would have posted a description of your hardware it would have been easier to conclude you had a nic in common and google would have immediatly confirmed it was the culprit.

ALWAYS post a complete resume of your install and your system even if it sounds silly!

And no hard feelings because you didn't, I just though it has to be mentionned, most problems once identified could have solved earlier if more info would have been provided with the first post...

Good advice, Hyksos.

I debated compiling the driver from source since I didn't want to deal with breakage when a new kernel is installed but I can figure out how to block the kernel from auto-updating.

Linux drivers weren't on the cd and there doesn't seem to be an official source for the source but I found an entry in the Linux MCE wiki that covers compiling and installing the atl1c driver where they link to a source package. Using that source I modified the makefile as instructed and built the driver. I renamed the original and manually copied the new module in place, rebooted and it works like a champ. Just don't strip the module like I initially did. The kernel won't load it if it's stripped.

So this one has a happy ending too...

Atheros driver saga

Glad things panned out and you were able to preserve the "feng-shui of the system".

I am having a bit of an issue compiling my own driver. I get the following result when I issue the make install command:

I remember having similar problems when I built the driver from my other system but I ultimately found a solution searching on Google. I am thinking I may get better results if I use a full Centos 6.2 install as a system for building.

Any suggestions...???

Please forward a copy of the source and compiled versions so that we can incorporate them into the build. Thanks!

Apologies for the late reply...

Silly, are you using the driver source linked to in the Linux MCE wiki? I didn't "make install". I just ran make and manually copied the driver in place (after renaming the old one). See if atl1c.ko exists in the src directory. If so, copy it to /lib/modules/<kernel version>/kernel/net/atl1c.

Ward, I am sending a tarball with the modified source and a compiled module to support a t pbxinaflash dot com.

Thank I rewrote things so the driver now works using make then make install then modprobe

This has been automated for new installs however if you dont have internet connectivity you will have to manually download it to a usb drive and install it by hand

FOR 32 BIT BASED SYSTEMS ONLY

wget http://pbxinaflash.org/piaf6/files/piafxtras-1.0-1.i686.rpm

FOR 64 BIT BASED SYSTEMS ONLY

wget http://pbxinaflash.org/piaf6-64/files/piafxtras-1.0-1.x86_64.rpm

to install

rpm -ivh piafxtras-1.0-1.i686.rpm

then

cd /usr/src/piafxtras

 chmod +x piafxtras-menu

 ./piafxtras-menu

Choose the last option


Then reboot and see what happens

This driver provides support for the Atheros L1C gigabit ethernet adapter found in the Asus EEE PC, newer Acer Aspire One machines, Dell Inspirion laptops, and numerous other netbooks and low-cost PCs.
