Description Miles Lane 2007-04-02 01:04:19 EDT
Description of problem:

I have a HP dv1240us with a mute button and a wifi kill switch button.
Each of these buttons have LEDs which do not work under FC7.  
In order to get them working, I have added:
    options snd-intel8x0 ac97_quirk=7
    options ipw2200 led=1
to /etc/modprobe.conf.
Also, to /etc/init.d/network, I added:
    echo 1 > /sys/bus/pci/drivers/ipw2200/0000\:01\:06.0/led

However, this is only partly working.
Under Ubuntu 7.04, these settings cause everything to work as expected.
I would like to either have code changes made in the intel8x0 and ipw2200 so
that these LEDs work without having to add these options, or I would like to see
these options added to the default modprobe.conf file.  These LEDs should "just
work" without user intervention.

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


How reproducible:


Steps to Reproduce:
1. Boot.
2. Connect to a wireless access point
3. press on the Mute button.
Actual results:

There are additional bugs which I will be reporting.  Currently, the mute button
is completely unusable (this was true before adding the option).  Also, I am
unable to get the WIFI kill switch to work.  So, the WIFI LED does light up as a
result of adding the option to modprobe.conf and the line to
/etc/init.d/network, but I cannot turn the signal off by pressing the button.

Expected results:

I expect these two LEDs two automatically work, without having to diddle with
the configuration files.

Additional info:

Another bug I will be reporting is that the LED on the WIFI button flashes about
once every three seconds during the entire boot process.  This indicated an
initscripts bug in that no connection should be attempted until NetworkManager
takes over and establishes a connection.

I think this should either be fixed upstream, by changing the driver defaults,
or (at worst, and this is not a good idea) in the Fedora kernel. I'm not sure
this justifies yet another hack in module-init-tools.

Why can't the led option just default to on?
