Comment 58 for bug 430809

Mario thanks a lot for debugging and fixing this. Everything mostly works now, just a small nitpick remaning:

I start w/ killswitch off (0), then switch BT off by software (1), the BT indicator LED turns off. Then I turn killswitch on (2) and off again (3); now the BT indicator turns on again although BT is disabled by software.

Below the output of dmesg corresponding to the numbers in parentheses above:
