Bug Description
The parameter led_mode on the iwlcore module defaults to 0 (blink on traffic). Having two blue, constantly blinking LEDS (this HP laptop duplicates the wireless LED) is unfathomably annoying.
I fixed it by installing an /etc/modprobe.
# 1 means do not blink
options iwlcore led_mode=1
This disables all blinking, including when associating. (It would be nice to keep the associating-blink, but I have no idea if this is possible.)
I think this file should be shipped by default (possibly under a different name), especially as the Intel wireless chipsets are most common on laptops, where a blinking LED in the peripheral vision is rarely a good thing.
In summary:
1) Ubuntu 10.04 LTS
2) linux-backports
3) I expected the wireless LED on my Intel PRO/Wireless 3945ABG, with the iwl3945/iwlcore driver, to default to not blinking.
4) It defaulted to blinking, possibly giving me a good start on a fatal aneurysm.
A quick look-through of the module source shows that the LED can only be set to "blink all the time" or "off when wireless disabled, on when enabled". The /sys/class/leds interface might have allowed more sophisticated behavior, but it seems to have disappeared in this version of iwl3945.
(By the way, thanks greatly for linux-backports -modules! It seems to have fixed the random disconnects issue I was having.)
