Subject: Disabling Bluetooth also kills WiFi

Hi!
With kernels 3.1 and 3.2, disabling Bluetooth via rfkill also disables
my wireless card on my HP Pavilion dm4. This didn't happen with 2.6.41
(I upgraded from Fedora 15 to 16).
My devices are set up as this (see attached output of lspci -vnn for
details about devices):
# rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
2: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
3: hp-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
11: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
The problem is, these commands also stop the WiFi:
rfkill block bluetooth
and
rfkill block 3 [for hp-bluetooth]
But this one only kills the Bluetooth:
rfkill block 11
Running
rfkill block wifi
does kill the WiFi, but leaves the Bluetooth up.
So it looks like the hp-bluetooth device is the culprit. Sadly, it's
what bluetoothd uses by default (if I judge by what gnome-bluetooth
does).
(If it matters, running 'rfkill block bluetooth' makes hci0 disappear,
and after unblocking bluetooth, it reappears with the ID increased by 1.
This doesn't happen with the WiFi.)
Please ask if I can provide more information/testing.
Thanks for your help.
