Red Hat Bugzilla – Bug 453565
Attansic L2 Gigabit network card not supported by kernel
Last modified: 2014-06-16 07:37:34 EDT
Description of problem:
Attansic L2 Gigabit network card (integrated on Asus P5LD2-X/1333 motherboard)
is not "seen" by kernel.
Version-Release number of selected component (if applicable):
kernel-2.6.18-92.1.6.el5 (stock kernel on a x86_64 CentOS 5.2 machine).
Steps to Reproduce:
1. Install OS on a machine with the Asus P5LD2-X/1333 motherboard.
Integrated LAN adapter is not recognised by kernel.
Integrated LAN adapter should work out of the box.
Machine's hardware profile, obtained via smolt:

Please be advised, that Bugzilla is not a support tool. It is an
Engineering and Community tool. So although all changes to Enterprise
Linux go through Bugzilla and Red Hat considers issues directly entered
into Bugzilla valuable feedback, there is no SLA around it.
If this is a production issue, please report it to your Red Hat Support contact.
Sorry, I've posted this here because the kernel is not supporting a *very
common* piece of hardware (Attansic L2 integrated network cards are present on a
large number of common motherboards nowdays - please see Asus).
So this affects a large number of users (and/or potential users), with no
special/uncommon hardware configuration.
It's especially bad for the marketing / popularity of a certain comercial
product (RHEL is *an excelent* piece of software, btw) that it cannot with all
facilities on *commodity* computers...
That's why I consider this *a bug* and I'll advise remaining so - IMHO.
Thanks a lot,
"that it cannot run with all facilities" etc...
I'll reopen this, since I've encountered *many* mainboards with the Attansic L2
chipset these days (especially from Asus).
Unfortunately, on the x86_64 platform, I was unable to find a working driver
even in .tar.gz format (in order to compile it from source). Despite indications
one gets various errors during compilation...
Atheros has become much more involved in upstream development recently, so we may be able to support this in RHEL in the near future. Please raise this issue through your support channel to ensure proper prioritization.

You might like to consider using the kABI tracking kmod-atl2 package (http://elrepo.org/tiki/kmod-atl2) that is available from ELRepo (http://elrepo.org).
This bug/component is not included in scope for RHEL-5.11.0 which is the last RHEL5 minor release. This Bugzilla will soon be CLOSED as WONTFIX (at the end of RHEL5.11 development phase (Apr 22, 2014)). Please contact your account manager or support representative in case you need to escalate this bug.
Thank you for submitting this request for inclusion in Red Hat Enterprise Linux 5. We've carefully evaluated the request, but are unable to include it in RHEL5 stream. If the issue is critical for your business, please provide additional business justification through the appropriate support channels (https://access.redhat.com/site/support).
According to my experiments, this bug seems to be fixed in CentOS 6.5.
