------- Comment #15 from [EMAIL PROTECTED] 2008-12-07 19:24 -------
In order to get the key work, we should make sure:
1. who can get the notification when hotkey is pressed. (both i8042 controller
and ACPI EC device in this case).
2. who can turn on/off the WiFi led.
I asked a wireless expert, and this is his answer:
1. usually, it's ACPI that can catch the hotkey press event. And it should
trigger an interrupt of the wireless device, which is probably done by the SMI
call.
2. this depends. there are some platform specific ways to turn off the wifi
led, or the wireless driver may control the led in some case.
Anyway, from the symptom described in comment #2, this seems like a wireless
driver problem, which doesn't disable the hardware correctly.
But we should make sure the ACPI notification is always sent correctly when the
hotkey is pressed.
In order to know which _Qxx method is evaluated, please apply the patch attach
below, enable EC debug option, and rebuild the kernel.
Then press the Fn+F2 hotkey for three times, and attach the dmesg output.
