iwlagn module ignores parameter "led_mode=1" under certain conditions

iwlagn module ignores parameter "led_mode=1" under certain conditions

[Toralf Förster]

Hello,

Since years this worked at my Gentoo system :

$ cat /etc/modprobe.d/iwlagn.conf 
options iwlcore led_mode=1

However nowadays this doesn't work when I do the following :

1. dock the ThinkPad T400 (no WLAN, only DSL)
2. boot it
3. s2ram it
4. undock it
5. go into the office
6. resume the undocked notebook (WLAN, no DSL)

The led is blinking ...

Putting however this line into the config file :
$ options iwlagn  led_mode=1

works always.

?

what kernel version you are using?
the newer kernel (after .38), the iwlwifi driver split into 2 separate
driver (iwlagn and iwlegacy). so there is no longer using iwlcore.ko

putting options "iwlagn led_mode=1" in config file should do the job.

2.6.39.1 and I'm just curious b/c if I boot the system within the office than 
the old line works fine.

Now you make me really confuse, so you use the same system, but work in
the office but not home? 2.6.39.1 already has split driver, so
"iwlcore.ko" not exist anymore, and it will not affect the led behavior.

what module parameters you have in the system, could you do the
following:
$modinfo iwlagn
$modinfo iwlcore

you should see the list of supported module parameters in iwlagn, but
not iwlcore.
