RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Răzvan Sandu 2011-12-05 13:50:18 UTC 
Description of problem:

My system contains a Gigabyte GA-H61M-S2P-B3 motherboard - smolt profile is here:

http://www.smolts.org/client/show/pub_33fc5191-e5c9-41c1-b3e6-3036f57bfe1a 

The mainboard features an Atheros integrated network card, which in not supported by default in RHEL/CentOS6.0 (but works OK with the "kmod-atl1e" package offered by the ELREPO repository - may be added after SO installation).

So I've added two identical NICs, D-Link DGE-528T, which work by default, being supported by the "r8169" kernel driver.

In this configuration, only ONE D-Link DGE-528T is "seen" by the system (and offered for configuration in anaconda, during system install).

Upgrading the kernel to the latest release (2.6.32-131.17.1.el.x86_64) does not help.


Version-Release number of selected component (if applicable):
2.6.32-131.17.1.el.x86_64  (tested on stock CentOS 6.0).


How reproducible:
Always.

Steps to Reproduce:
1. Install a system with two identical "r8169" network cards.
2. Observe system's behaviour during installation and afterwards (including the moment after installing the latest kernel).

  
Actual results:
The system:

- shows only ONE "r8169" network cards (when two identical ones are physically installed)
- does not see the Atheros network card without installing third-party software

Expected results:
All network cards should be enabled by default and should work correctly.

Additional info:
Please look into bug #725193 also, which may be related to this.

After adding the "kmod-atl1e" package from ELREPO, the Atheros NIC becomes visible and works OK.

Now "lspci -v" shows the following for the three NICs:


Atheros:

02:00.0 Ethernet controller: Atheros Communications Device 1083 (rev c0)
	Subsystem: Giga-byte Technology Device e000
	Flags: bus master, fast devsel, latency 0, IRQ 31
	Memory at fbec0000 (64-bit, non-prefetchable) [size=256K]
	I/O ports at df00 [size=128]
	Capabilities: [40] Power Management version 3
	Capabilities: [48] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Capabilities: [58] Express Endpoint, MSI 00
	Capabilities: [6c] Vital Product Data
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [180] Device Serial Number ff-83-e9-c2-50-e5-49-ff
	Kernel driver in use: atheros_eth
	Kernel modules: atl1e


First D-Link NIC (functional):

04:00.0 Ethernet controller: D-Link System Inc DGE-528T Gigabit Ethernet Adapter (rev 10)
	Subsystem: D-Link System Inc DGE-528T Gigabit Ethernet Adapter
	Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 17
	I/O ports at ee00 [size=256]
	Memory at fbdff000 (32-bit, non-prefetchable) [size=256]
	[virtual] Expansion ROM at dc400000 [disabled] [size=128K]
	Capabilities: [dc] Power Management version 2
	Kernel driver in use: r8169
	Kernel modules: r8169



Second D-Link NIC (non-functional - seen as a video device ??!):

04:01.0 Non-VGA unclassified device: Gammagraphx, Inc. (or missing ID) Device 0002 (rev 10)
	Subsystem: D-Link System Inc Device 4300

As you clearly state, you are running CentOS, so please file the bugs with
your distribution provider, ie. CentOS.

@Jes

I hoped this is useful to official Red Hat, too. Switched this to bug 5288 in CentOS' bugzilla.
