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 Matt Domsch 2011-02-22 16:30:07 UTC

+++ This bug was initially created as a clone of Bug #679471 +++

Description of problem:
biosdevname suggests emX names for PCMCIA/PCCard devices.  This is arguably incorrect.

Version-Release number of selected component (if applicable):
0.3.7-1


> Let's look at the first device.

> BIOS device: em1
> Kernel name: eth1
> Permanent MAC: 00:0A:CD:17:99:FD
> Assigned MAC : 00:0A:CD:17:99:FD
> Driver: r8169
> Driver version: 2.3LK-NAPI

It's a second PCcard in the docking station, just for testing

> BIOS device: em2
> Kernel name: eth2
> Permanent MAC: 00:00:21:0F:8C:C4
> Assigned MAC : 00:00:21:0F:8C:C4
> Driver: 8139too
> Driver version: 0.9.28

First PCCard in the notebook's PCCard slot



I'm not at all sure what the right thing to do here is.

any solution for this?

Comment 4 Matt Domsch 2011-06-21 15:20:41 UTC

Adding Jordan and Narendra to close.

Comment 6 RHEL Program Management 2012-07-10 08:36:43 UTC

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 7 RHEL Program Management 2012-07-10 23:07:45 UTC

This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.

Comment 9 Václav Pavlín 2013-04-02 11:48:01 UTC

Jordan, Narenda, could you please take a look at this?

Comment 10 Narendra K 2013-05-15 19:26:57 UTC

Hi, fix for the issue is being explored.

Comment 11 RHEL Program Management 2013-10-14 05:19:41 UTC

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in

Comment 12 jordan hargrave 2014-01-16 16:13:27 UTC

Not planning on supporting this.  Need to add a rule to biosdevname rules to exclude PCMCIA cards.

Comment 13 Narendra K 2014-06-13 17:10:37 UTC

It seems like the following patch would result in not naming PCMCIA cards as it checks for SUBSYSTEMS=="pci". As this check will not succeed for PCMCIA devices, they will not be named.

SUBSYSTEMS=="pci", PROGRAM="/sbin/biosdevname --policy physical -i %k", NAME="%c",  OPTIONS+="string_escape=replace"

Comment 14 Sreekanth Reddy 2014-12-10 17:22:22 UTC

Verified in the latest BIOSDEVNAME and is fixed.
Hence closing the bugzilla.
