Red Hat Bugzilla – Bug 591226
b43-phy disabled after resume from suspend
Last modified: 2011-06-27 12:17:14 EDT
Description of problem:
b43 driver turns radio killswitch off after resume
Version-Release number of selected component (if applicable):
Do a suspend resume
Steps to Reproduce:
Wireless is disabled
Wireless should be enabled.
Running on a lenovo S12 laptop with broadcom BCM4312 card. NetworkManager is activated but Wireless cannot be actived after resume from suspend. /var/log/messages displays:
kernel: b43-phy0: Radio hardware status changed to DISABLED
kernel: b43-phy0: Radio turned on by software
kernel: b43-phy0: The hardware RF-kill button still turns the radio physically off. Press the button to turn it on.
Firmware is version 478.104 (2008-07-01 00:50:23)
Switch the radio button has no effect.
"rfkill list" displays the device is hard blocked
rfkill unblock device gives no message but doesn't change the status, the problem remains.
Please attach the output of running "rfkill event" while working the rfkill switch. Make sure you are manipulating the correct switch -- for example, my T400 has not only the Fn-F5 'soft' switch but also a slider switch along the front edge (i.e. near the latch).

John, thanks for your input, but be aware that I'm not using any switches. I'm just suspending the machine...on resume the rfkill list shows the Wireless LAN as being hard blocked, but the position of the killswitch has not changed.
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. 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bug reports from releases that are no longer maintained.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 '13'.
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 13'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 13 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:
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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.
