Description Akemi Yagi 2010-04-13 19:51:28 UTC

Description of problem:
LED support in iwlagn and iwl3945 drivers (IWLWIFI_LEDS) was enabled in RHEL 5.4 but is now disabled in RHEL5.5.  Unless the change was made on purpose, this is an error in the configuration of the 5.5 kernel.

Version-Release number of selected component (if applicable):
2.6.18-194

How reproducible:
Always

Steps to Reproduce:
1. Turn wireless on 
2. Check the wireless LED
3.
  
Actual results:
The wireless LED does not work

Expected results:
The LED light should come on

Comment 2 John W. Linville 2010-04-22 19:05:19 UTC

Have you done a build w/ that option enabled?  Does it make the lights work for you?

Comment 3 Phil Perry 2010-04-22 19:57:47 UTC

Yes. A CentOS cplus testing kernel that is a rebuild of the RHEL5.5 kernel with LEDs enabled, and I can confirm the wireless LED works as expected for iwlagn (iwl4965) wireless.

As noted in the report, LEDs were active in RHEL5.4 and are now not active in RHEL5.5.

Akemi Yagi (the original reporter herein) built the kernel so can supply the config if required.

Here's the line to look at:

$ grep IWLWIFI_LEDS config-2.6.18-164.el5  <== RHEL5.4
CONFIG_IWLWIFI_LEDS=y

$ grep IWLWIFI_LEDS config-2.6.18-194.el5  <== RHEL5.5
# CONFIG_IWLWIFI_LEDS is not set

Comment 5 John W. Linville 2010-04-23 14:41:37 UTC

Yes, clearly an oversight.

Comment 7 RHEL Program Management 2010-05-20 12:42:03 UTC

in kernel-2.6.18-200.el5
You can download this test kernel from http://people.redhat.com/jwilson/el5

Detailed testing feedback is always welcomed.
