ath6kl_sdio blocked by RFKILL

ath6kl_sdio blocked by RFKILL

[Ulf Samuelsson]

Have built the ath6kl_sdio driver for an Cortex-A5 chip using the 
linux-3.6.9 kernel
File system built using Yocto  and Busybox RF-Kill.

Kernel Config contains:

CONFIG_RFKILL=m
CONFIG_RFKILL_LEDS=y
CONFIG_RFKILL_INPUT=y
# CONFIG_RFKILL_GPIO is not set

When I do

# ifconfig wlan0 up.

I get the error message:

ifconfig: SIOCSIFFLAGS: Operation not possible due to RF-kill

If I run "rfkill list" I get

1: phy1: wlan
         Soft blocked: yes
         Hard blocked: no


If I try to unblock using "rfkill unblock all" or "wifi" or "wlan", the 
soft block remains.

Any clues?

Looking through the Busybox rfkill code, this seems to generate an event.
What is supposed to react to this?
Could there be a rule, which is missing?

Have you tried "rfkill unblock 1"?

Yes, I have now been able to reproduce on another board.

The System has an MMC connector, and if I boot with my SD51 SDIO card in 
the connector, then

"rfkill unblock <x>"

won't work, with x = {all,wifi,1 ...}

If I boot without the SD51 card beeing inserted, and then insert if 
after theboot has been completed,
then rfkill works as expected.

The MMC host driver is  built as a module, maybe it shouldn't.
