    ath5k: ignore the return value of ath5k_hw_noise_floor_calibration

    Noise floor calibration occasionally fails on Atheros hardware.
    This is not fatal and can happen if there's simply too much
    noise on the air. Ignoring the calibration error is the right
    thing to do here, because when the error is ignored, the hardware
    will still work, whereas if the error causes the driver to bail out
    of a bigger configuration function and does not configure the tx
    queues or the IMR (as is the case in reset.c), the hw no longer
    works properly until the next reset.

At a time when there is a "bail out of a bigger configuration function" computer, namely the kernel, begins to slow down. And it affects the whole system. The program "top" can not show it. The mouse cursor begins to move jerkily. There is a strong decrease in connection speed.

Comment 2 Bug Zapper 2010-11-04 01:12:25 UTC
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12.  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bug reports from releases that are no longer maintained.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 '12'.

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 12'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 12 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 issue

Fedora 13 contains a different bug. This can be closed.

Comment 4 Bug Zapper 2010-12-04 00:32:18 UTC
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 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no longer maintained, which means that it will not receive any further 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.
