Wireless LED always on

Wireless LED always on

[Gordian Klein]

Hello,

i have a Sony Vaio SVS1511V9EB with an Intel(R) Centrino(R) Advanced-N
6235 AGN wireless card. The card is working fine, but the wireless LED
on my laptop is always on. No matter if i disable the wifi device via
NetworkManager or "rfkill block all". I set the iwlwifi led_mode
parameter to 1 (and to 2 for testing), but this didnt do anything to the
LED, it was constantly on. Id like it to be off when the wifi device is
disabled.
This is a log of dmesg:

# dmesg | grep iwl[    3.955915] iwlwifi 0000:02:00.0: irq 46 for MSI/MSI-X

I verified the led_mode parameter is set correctly with :

# cat /sys/module/iwlwifi/parameters/led_mode
1

I am running openSuse 12.2 x64 with Kernel 3.9.3-10.g06ad9d8-desktop.

Thanks for any hint.
