Description Mike Fleetwood 2009-10-12 11:33:16 UTC
Description of problem:
On my Asus EeePC 1000HE netbook with Fedora 11 the keyboard toggle of the WiFi transmitter, Fn+F2, use to work perfectly.  However since upgrading from kernel 2.6.29 to 2.6.30 this stopped working.


Version-Release number of selected component (if applicable):
kernel-2.6.30.5-43.fc11.i686.PAE


How reproducible:
Always


Steps to Reproduce:
1. Boot with 2.6.30 kernel
2. Login
3. Press Fn+F2


Actual results:
WiFi transmitter not toggled on or off.


Expected results:
WiFi transmitter toggled on and off. 


Additional info:
In Fedora's 2.6.29 kernel rfkill and rfkill_input were compiled into the kernel, however in 2.6.30 it became a loadable module.

-CONFIG_RFKILL_INPUT=y

+CONFIG_RFKILL_INPUT=m

Under kernel 2.6.30 the rfkill module is automatically loaded, however the rfkill_input module is never loaded.
 [mike@edge ~]$ lsmod | fgrep rfkill
 rfkill                  8928  5 ath9k,eeepc_laptop

Workaround is to add the following line to /etc/rc.d/rc.local to load the kernel module at bootup.
 modprobe rfkill_input

Comment 1 Mike Fleetwood 2009-11-01 22:15:30 UTC
The Fn+F2 key works perfectly on my Asus EeePC 1000HE netbook with freshly installed Fedora 12 Beta.

It works because rfkill_input is compiled into the kernel.

[mike@edge ~]$ fgrep RFKILL /boot/config-2.6.31.1-56.fc12.i686.PAE 
CONFIG_RFKILL=m
CONFIG_RFKILL_LEDS=y
CONFIG_RFKILL_INPUT=y
CONFIG_RT2X00_LIB_RFKILL=y

Relevant fragment from the kernel RPM change log.
[root@edge ~]# rpm -q --changelog kernel-PAE

  - CONFIG_RFKILL_INPUT=y (used to be =m, which was invalid)

Comment 2 Bug Zapper 2010-04-28 10:48:16 UTC
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '11'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 11's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 11 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 3 Bug Zapper 2010-06-28 15:00:19 UTC
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
