Bug#684352:

[David Smith <sidicas2@gmail.com>]

Miho:/home/david# rfkill list all
0: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
Miho:/home/david#


When I turn off the Wifi using the network-manager-kde tool, rfkill then shows this:

Miho:/home/david# rfkill list all
0: hp-wifi: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
Miho:/home/david#


At which point, neither the network-manager-kde tool, nor the wifi hardware switch on the laptop is able to turn
the wifi back on.   The "enable wireless" is disabled / greyed out in the network-manager-kde tool because it
thinks the wifi is hardware blocked when it isn't.  rfkill also shows the wifi as hard blocked.    However, using rfkill unblock all results in this:


Miho:/home/david# rfkill unblock all
Miho:/home/david# rfkill list all
0: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
Miho:/home/david#


I can then turn the wifi on again in network-manager-kde and connect to a network in the network-manager-kde tool because it thinks the wifi is no longer hardware blocked.


Again, booting the kernel with ACPI=off, this whole problem just goes away and I have only one wireless lan device which I can control freely with network-manager-kde without having to keep calling "rfkill unblock all" everytime I turn off the wireless with software.
