Description Stephen Rowles 2008-07-15 19:44:46 UTC
Description of problem:

Wireless hardware on Acer 5920 laptop (iwl3945) gets switched off when the
wireless key is pressed, or the laptop dies due to a flat battery. When this
happens it is impossible to re-enable the wireless from Linux. My only choice is
to reboot to Vista, which I fortunately decided to dual boot rather than go pure

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

Fedora 8 #1 SMP Fri Jun 27 16:25:53 EDT 2008 i686 i686 i386 GNU/Linux

How reproducible:

1) start linux
2) connect to wireless network
3) allow laptop to power fail
4) restart laptop, notice that wireless button does not light up
5) following messages appear in dmesg:

iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux,
iwl3945: Copyright(c) 2003-2008 Intel Corporation
iwl3945: Detected Intel Wireless WiFi Link 3945ABG
iwl3945: Tunable channels: 13 802.11bg, 23 802.11a channels
phy0: Selected rate control algorithm 'iwl-3945-rs'
iwl3945: Radio disabled by HW RF Kill switch

Comment 1 Bug Zapper 2008-11-26 11:00:20 UTC
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  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bug reports from releases that are no longer maintained.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 '8'.

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 8'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 8 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:

Comment 2 Stephen Rowles 2008-11-28 11:29:20 UTC
This bug is no longer applicable to Fedora 10. Using fedora 10 live CD wireless can be switch back on (by turning of wireless in network manager, then re-enabling). 

Still not ideal, it should be switch on during boot if the network manager has it as enabled. I will raise a new bug to cover that on Fedora 10.
